Craziest fix that actually worked

One time??!@#! :omg: It must be kind of a reusable solution, 'cause I've used it myself several times in my own life. Wait... that just rang a bell... a pattern, I think is what they call it. A pattern!

Our company has to reboot our Win2008R2 server every morning at 6am so it performs right during the day. I think it's mainly related to our ERP system (Epicor) but it seems to work. I've worked with VMS systems that under a HEAVY load have way over a year of uptime with no problems, we had to shut it down to replace a hardware component :(

I'm just curious what the most surreal fix to a problem you've ever ran into has been?

I once wrote a 6502 routine, running off an interrupt, to modify a single bit in memory when a particular byte of memory had a certain value. This allowed me to move the game "Frak!" from cassette tape to disk - as the anti-piracy software flipped the bit occasionally resulting in a rather amusing Captain Pugwash based "you're a Pirate" screen.

Well, this is not the craziest fix but the craziest bug hunt:
MaxValue= 0;
for (I = 0; I < N; I++)
{
Value= SomePositiveFunction(I);
if (Value > MaxValue)
{
MaxValue = Value;
MaxI = I;
}
}This piece of code obviously finds
MaxI, the first indexIthat achieves the largest value of the function (in case of ties), doesn't it ? Well, no. It was returning the last such index ! The reason was internal FP rounding, making it such that right after the assignmentMaxValue = Value, the relationMaxValue < Valuedid hold !! Took me ages to understand that, debugger not showing what was actually going on. The fix: use the/fp:precisecompiler flag. -

A coworker had a SQL query in MS SQL Server that didn't run at all. All it did was process the query for a looooong time. My coworker entered a random line break somewhere and the query ran instantly. Weirdest performance fix I've ever seen... I've been searching for a problem in C#. I was using some library from a different solution which I had built myself. I encountered a bug, fixed the library and everything worked... For a few runs at least. Out of nowhere the bug came back. I spent the whole afternoon trying to fix it, but I got MessageBoxes that weren't there anymore, errors that could not be explained etc. Restarting VS2010 finally did the trick... Another great hack I've used: in a live production we print some files and save these files to disk and call them something like 'File+date+time+milliseconds'. Then our client got a new server and the files weren't saved to disk anymore because the filename was already used! Obviously the new server was so fast it could print and save two files in the same millisecond... A Thread.Sleep(500) fixed the problem! We've actually used that solution more than once... Although it's not something I'm particulary proud of, it does the job.
It's an OO world.

In the before the before, I worked for a company that had a COM+ solution written in VB6. They sold the solution to a company that would not open their firewall for COM+ so I wrote a C++ server to map COM+ function calls over port 80 which they would allow. Crazy.

I had to adapt a very, very legacy 6502 DA system intended for remote operation to local working. The system used a dialler to establish a phone connection and then tickled the modem to pick up the line (yes it was THAT old) and then squirted data to a remote Vax/VMS system in ASCII/Hex. Using just an 8086 PC and MSBasic I managed to emulate the dialler, the modem and the remote system - this worked perfectly for years.

Many years ago we had a program that printed delivery notes on form feed dot matrix printers. One customer bought a slightly different printer that we hadn't used before, and we couldn't stop it spooling a blank note after each one it printed. I inserted control codes at the end of the print so that after each delivery note printed, a blank one would spool, then the printer wound it back in again.

The most surreal aspects of what I could contribute are in the problems, not so much in the solutions. Rewriting something letter-by-letter worked several times with me, too. And there were no hidden letters or non-breaking spaces in the original. In a VB6 program, we got runtime errors when the program was run under Windows XP, but not when run under Windows 9x/ME/2000. Most annoying thing was, the error was reproducible only in the compiled program, but never in the development environment. Took us weeks to find out. Turned out it was using modal dialog windows (from the MsgBox function) in the GotFocus event handler. I don't remember the fix we used, though. In VB6, the SendKeys function ceased to work properly under Windows Vista. So I programmed a function that performed the needed keystroke actions one after the other. The weirdest issue we ever encountered is the following, I think: Some clients from Switzerland got a "path not found" error when running one of our programs, but it worked fine with most clients. During tests with several different Windows versions, no problems of this kind were ever encountered. Turned out it were only French-speaking clients that got that error. But setting the system language to French didn't reproduce it. Luckily, we had an MSDN abo that time, so we could legally download and test a French Windows version (I don't remember whether XP, Vista or 7; maybe all of them). Here, the error suddenly was present. A short investigation revealed that the API call for a path "plenked", i. e. it put superfluous spaces before punctuation marks - and the backslash was a punctuation mark too, seemingly. (Note: in French, spaces before punctuation marks except the full stop are required.) Solution was simple: Remove all spaces immediately before and after backslashes in a path.

Blame that on shit programming. We have the same problem here, the reason? some bastard java programmer thought it would be fun to place a hibernate context (or whatever they're called) on the session on a web app, every single request. At every single action on the web app. Needless to say that even if we had the time to fix it, nobody understands what the hell is going on on that application. all we know is that perm gen blows up hourly. So now we have a job running on the server to run the GC every once in a while. Your case is probably easier, maybe it's just a config that is suboptimal, one of the server-restart-required apps here is a 1998 asp + vb6 app that got the threading model switched. In that case the app was recompiled, but maybe there's something you can do about the ERP that does not require a recompile...

A batch program (DCL on VMS (5?) circa 1990) that I had to delete and type in again because the system refused to execute it. :sigh:
I've had to do that loads of times in various environments. Notepad for JavaScript code is notorious. I guess that it is somehow getting some control char that it does not bother to display. Yes, I know that I should be using something other than Notepad (and, yes, something other than JavaScript), but I'm in a locked-down environment where I am not allowed to load or run any unapproved software (which is unhelpful for a software developer).

One company I worked for rebooted their Red Hat box every day at 4 in the morning, otherwise it would inexplicably freeze and drop messages (ie. money). It was not the OS's fault though, it was the crappy java/jboss app that did the messaging from the mainframe to swift and back. The log files it produced were over a gig each day and everyone spent some jail time sifting through them to try figure out what exactly caused the freeze. AFAIK they are still rebooting them every day.

That is hilarious. I actually a lol moment when I read that. So all these years that I've made fun of people that continuously "exercised" their mouse while waiting for results (I've been guilty myself) and you're telling me that it's a legitimate solution? Too bad they don't give the explanation behind why the method works.

A person that used Scantron sheets for data entry upgraded their computer. After the upgrade, the computer could no longer communicate with the Scantron reader. It was a simple RS-232 interface. Reconnecting to the old computer, I noticed that the Scantron "ready" light would activate for about 30 seconds during which time the sheets would be successfully fed. With the new computer, the Scantron "ready" light would activate for about 0.2 seconds. Solution: toggle "Turbo" mode off for reading Scantrons. This gave them about a 5 second window to feed the sheet. Dang hard coded delay loops!

I once had network problems at 10:12 am every morning. It turns out that the static electricity produced by office staff walking on the carpet at the office was running up an unplugged cat5 cable short circuiting the cheap hub we had. Unplugged the cable from the hub completely and no more problems. craziest problem i have ever had to solve.

My very first paid job involved some Fortran development on an IBM360. I'd go home at 5pm each day, having logged out and powered down my terminal. (I don't recall what system we used, but this was 1977). Each morning I'd find the other staff scratching their heads about the mysterious crash of the '360 the evening before. This happened each day for a week until I overheard one of them saying "the only thing I can think causing it is someone's powering down their terminal". I left my terminal on after that and the daily crashing problem "went away". I never did own up.

Ah, port 80 is really a bad idea. The default port of Skype is 80 and the XAMPP server's too. And i don't imagine working without skype and/or youtube
Microsoft ... the only place where VARIANT_TRUE != true
What a weird response, suggesting that somehow skype an use port 80 and not interfere with XAMPP but that somehow my code would have a problem. Normally, I would just say it is a little too late to go back to that decade and change code mandated by a very large client who would only open port 80 and just say, but only because I think honesty is the best policy, maybe you should go and learn how TCP/IP works.

It happens with hardware, too. Our satellite dish would simply not track the damn satellite. I fixed it by disconnecting a blue wire. No idea what that particular blue wire was connecting...there were hundreds of them in there and we didn't have detailed schematics available. And, yes, the report we sent in closing the ticket did say "disconnected a blue wire". :laugh:
