Is this normal?

[PaulowniaK]

No way am I a programmer! ;P I got through the computing science bit of my degree by copying and pasting other people's code!! Oh, hang on... I still do that... Anyway, memory is another thing I'm never so sure about. I am aware of the concept and the consequences of getting it wrong, but I don't know enough to know for sure what I'm typing is sensible... Better have another look to see if I'm mangling pointers or something... :~

It may happen, while you shouldn't mess up with threads that way. :)

Nor do I. Stop what you are doing and get a different job. And yes, you can quite easialy lock the machine with threads it all depends on priority, have yiou been messing with thread prioirity too?

Happens all the time, I reboot every night and I expect a lock up a couple of times a week. I figure every time I hit a bug while developing there is a little bit of crap left over and it sort of accumulates in the corners. Needs a cold boot to clear it out. I mean I have had this issue since early 90s when I started writing excel macros, not a lot has changed in this area, I can still manage to crash a computer regularly.

Oh dear :sigh: Threads and the unexperienced are a recipe for disaster.

All right, you guys, I got eight crates of Ipecac from Mort. All on my tab. Now, whoever goes the longest without puking gets the last piece of pie in the fridge.

With threads this is quite possible. If you are doing work like this get your manager to OK buying a couple of decent books.

There's a verrrry good article Here[^]. It might take a bit to wade through it, if you're unfamiliar with the language/syntax, but the logic and usage are impeccable.

Odds are you have runaway threads, which cause a system to appear locked up.

Most likely...:thumbsup:

Thanks for the info.:thumbsup: It's quite hard, but I'll try reading it.

You know, you wouldn't do open heart surgery without training and experience, the same goes with software engineering.

True... but it's not so common that you kill someone by writing bad code... I'm sure you can (f-ing up the software used in air traffic control, say) but in my case, the worst that is going to happen is that some ionized molecules are going to go to ionized molecule heaven.

There are two usual causes to freezing machines: 1) Memory leaks: Watch your memory usage in Task Manager. Does it rise faster than you can explain? Then you very likely forgot to free the memory of some objects which you create in a loop. 2) Never ending loops: Watch you CPU time in Task Manager. Does it reach 100% before the machine freezes? Then very likely a break condition is never reached (i.e. you loop over a list, but forget to increment the index). As you are unexperienced, only a debugger can save you.

This statement is false.

That was a brilliant response to the inaccurate comparison. :thumbsup:

You will never learn, unless you try. Succeed or fail, don't give up. Assuming of course you actually like what you're doing/learning. Never listen to another's notion that you "can't" or "shouldn't". Yes, malformed threads can cause the behavior you are experiencing, and they will extend to the end-user unless corrected.

[Jason Christian]

If you're not a programmer you might want to convince someone to let you program in something other (i.e. easier, or more forgiving) than C++.

[Jay Elston]

Actually, you _can_ kill people with bad code. You should subscribe to comp.risks. It is replete with stories about how software causes death or destruction.

I am reminded of a quote that I read many years ago, and I cannot remember who said it: "'C' will allow you to shoot yourself in the foot. 'C++' makes it harder, but if you succeed, it will take off your whole leg." :laugh:
