Amuled is running now happily with more than 2000 files in "waiting" state.

It still gives Wx errors occaisonally.


Same in 9596, although it does seem a bit more stable - in general it's up about 6-8 hours between crashes.

That's not a helpful problem report.

Well  I don't think the Wx error is related to the number of files being downloaded anymore.

Where do you want any crash reports pasted? Here or the crash/bt forums?

Amuled: SVN 9605,  ~140 downloading, 1200 waiting, 800 paused.

It seems to fall over when a file is completing or just afterwards but it's hard to be sure because of the infrequency of crashes (about 3-5 hourly)

Things do seem to crash far more often if amulegui is running, or has been running.

Not a crash, actually. But interesting nevertheless.

The program dies when this happens. What would you call it? :)

You are running amuled in debug mode. In debug mode it may crash controlled if it finds itself in a situation that looks like a bug. In this case it has just dropped a slower client but still finds nothing left for downloading.
Are all of your "crashes" like that? Then simply compiling amuled in Release mode should solve your problem.

So, if I understand correctly, for production use is always better to disable the debug?
I hate to tell users to download the debug version only for post a decent backtrace.

Yes they are all like that. Good to know this is just debugging in the SVN compilation.

Ehh? So we should not compile aMule in debug mode?  ???

We had such issues before.
Debug mode means not only availability of debug symbols, but also lots of wxASSERT() checks. Many of these just cause a controlled abort before the program would crash anyway (like checking a pointer for zero that is dereferenced in the next line). Others are just mean to trigger a debug breakpoint so a developer can examine some unexpected behavior. These can of course turn into a nuisance for end users who just want to run the app.

On the other hand - if you run a SVN version you should be aware that you are beta testing, and feedbacks of such asserts are valuable assets to get the software stable. So SVN versions should be compiled in debug mode. stoatwblr, if this issue is biting you you can just remove that one wxFAIL. We may come back to you to request additional information (like patches with extra debug prints) if we want to get to the cause of the problem.

I've left debugging on but have disabled "DropSlowSources" for the moment.

Let's see if anythign else breaks... :)
