How would you solve that?

Maybe use ProcessExplorer to see what threads it's creating. Maybe there's a thread that is leaking the memory, and yet another bug is that when you stop the service, the thread isn't being stopped. Of course, you're not getting paid to find their bugs! I'm curious, what kind of software works only with one kind of software repository? Marc
We are using a specific software to program the PLC's and CNC's, this software is like a text editor but it stores all the text files we modify in one big binary file. If we want to track our changes without major issues we need their interface to subversion, in fact, at the end we have subversion running, but the interface between the software and the subversion repository is faulty...

Hello all, in our department we are using a software that works as a software repository (a kind of subversion) that is the only one that exists/works for the software that we are using. It seems that the service that runs on our server (the one that handles all the queries from our computers) leaks memory. Even if I stop the service it doesn't frees all the memory that it has occupied. I've tried to speak to the manufacturer of that software without result... My only guess is to set up a virtual machine in order to serve that service and make it to reset each day. Any other idea? this is like killing a fly using a thermonuclear bomb... :~ As always thank you in advance.
Use a virtual machine, VMWare or something like that, install an OS inside and let the app run inside it without compromising the entire server, if the app crashes or eats all the VM asigned memory, well, you will still have the chance to reset the VM without bringing down the whole server, all other options will eat most of your free time and probably not going to fix your problem. Regards.

Get one of those timer plugs. Every night at midnight it switches off and then on. Server reboots. Memory leak fixed. (Had a friend who had his computer on a timer plug. I gave up explaining why it wasn't a great idea.)
cheers, Paul M. Watson.
Ahhh... I see, I see... I'll place a UPS after the timer plug and then I'll program the UPS service into the server in order to stop automatically the server after a power cut... Nice solution Paul! :rolleyes:

Since you can't seem to get them to fix the problem, why not start a blog or website called acmesoftwarerepositorysucks.org - and then blog it to death. Make sure the site is SEO. If that company isn't totally stupid, they'll realize that the publicity will hurt their reputation, and they just might "adjust" priorities.

You're right. These facts that you've laid out totally contradict the wild ramblings that I pulled off the back of cornflakes packets.

I am confused on this part...how is it that your version control needs to be so specific? Most version control software is language/platform independent. In any case, I would recommend getting as much information about the leak as possible. Run some performance tests and isolate exactly when the leak occurs. Software companies who are usually too busy/lazy to fix bugs on older versions of software might be more apt to help you (and other customers who are having the same problem) if you can tell them exactly when and where the problem occurs. Setting up a VM and restarting it every night might be your only "solution" now, but this sounds like an awful way to go about things and it should be completely unacceptable to you and your management team...but you might be stuck :(

Good for you - I too don't have a blog, in fact, I refuse to start one. Got better things to do as well.

If the memory isn't recovered when the service is shut down, this is a bug in windows. When a process exits, ALL resources used by that process are freed. Anything else is a serious problem. I'd suggest the memory is going somewhere. Something else besides the service...

There's a couple of ways a program can acquire global resources that will "leak" when a process terminates if they're not freed correctly, e.g.: Memory allocated with GlobalAlloc(), SysAllocString() (& variants) - These resources are valid across process boundaries and if they were automatically released when the allocating process terminated could leave any number of other processes in an indeterminate state. If a GlobalAlloc() handle didn't remain valid after process termination, the clipboard would only ever work while the source application remained active! Out-of process OLE object references (not sure if the default marshaller is supposed to track AddRef/Release counts & perform appropriate releases on process termination, from experience I can only say that I doubt it).

Eh? I may be missing something here but doesn't stopping the service require terminating the service's primary thread (actually a thread in the SCM that calls the service entry points)? & once a program's primary thread terminates, any remaining secondary threads are forcibly terminated? Or perhaps the service launches & communicates with a secondary process & it's the secondary process that's leaking memory?

How about installing something like a ram optimizer clickety - basically it tries to free memory once the available memory falls below a certain level which you configure. Guy

They are just BS, they just use up all your memory so that existing used memory is moved to your swap file.

There was an interesting anecdote included in an article back in the '80s about an American who'd taken a position with a Japanese company. It seems his group had a problem with the control software for some component they used in manufacturing their product. By habit, they'd debugged the code and found the solution to the problem, then came to their new supervisor with the problem and solution. He reported telling them, "Next time, just report the problem, and we'll let the vendor solve it." I have questioned his logic ever since. This is based on my own experience that most software vendors (not all, by any means, and the percentage seemed to go down for a while) will resist any input that their product has a bug - unless, of course, if you could prove it AND you offered a solution for it. Comments, anyone?

The Virtual server sounds good but just for argument's sake you could try to write a program that will allocate and then deallocate every single bit of available memory once the service has been stopped. Then restart the service. I would not put my hand in the fire for this method but it may be worth a try - any other non-reboot ideas ?

Yes, VM or hardware is the only way to solve a leak that even the OS can't reclaim upon process termination. Of cousre, it also means the OS has a bug, so I'd opt for a hardware solution, or at least a VM made by a different vendor. However.. why are you still using this product, anyway? If the product is really all that bad, and they are not planning to have a fix out for a year (don't forget, plans are always optimistic), aren't you staying with a product whose customer base is defecting? Is that really the horse you want to hitch your company's source code to? I've seen companies fold over such fiascos and wouldn't want to risk my company's source code to a company about to fold with such a serious flaw already in their software. Maybe that's just me though.

Go into the services manager and double-click on the services involved. Look at the top of the dialog for Service name:. Now create a batch file with the following:
sc stop *service name goes here*
sleep 30 ; give it some time to shut down
sc start *service name goes here*Now go into control panel and Scheduled Taks > Add Scheduled Task We had to do this for a 3rd party app which kept dropping its database connection (probably during nightly backups) and wouldn't automatcially restore the connection. The only way to fix it was a restart. So we setup a scheduled task to start and stop the services during the night so all would be good in the morning when the service would acutally get used.
Todd Smith
Likely wouldn't work in this situation- he's reporting that the service isn't deallocating memory on shutdown.
