This story goes from 2.3.1 when it was true, but the crash happened from time to time and with more stress (more active downloads, like 100). With SVN version (2014-10-23) aMule does not live through the day with even less stress.

The key issue is here how many active downloads there are (active - they are actually downloading, not in idle, waiting, state). If they are about 30 (for SVN) the limit is reached and amule crashes. It is not related to download speed limits (IMHO), all downloads in total could take around 20% of the speed limit of amule, and the crash will happen as well. However I don't know what happens in the actual moment of crash, if there is no some spike of the download speed.

It could be just conincidence, but when I run amule from gdb in order to get the stack trace amule worked for several hours (without it it would be 2-3).

Here is the dump from gdb:

Please let me know if you need some other information.

[GonoszTopi]

Hmm... Could you try and test aMule with Boost ASIO networking? For that you'll need to have Boost >= 1.47 installed and configure aMule with --with-boost (or if you don't want to install Boost, use --with-boost=/path/to/boost/sources).

[lumi]

Thank you for the reply and hints how to rebuild aMule. I hope it is not just pure good luck, but I rebuilt aMule with boost and it works just fine for several hours now without single crash. So it seems boost did a trick.

[GonoszTopi]

Looking at your backtrace it seems that the crash was related to wxWidgets networking code. That's why I suggested Boost.Asio. It's good to hear that it seems to work.

Another thing that might worth a try, compiling aMule with the latest stable version of wxWidgets, 3.0.2. However, please note that wx-3 support in aMule is currently in the "experimental" state...
