Details

The amule 10832-2 package compiled with wxgtk3 has a memory leak that consumes all available memory and swap, locking up and eventually killing the system. In my setup this occurs when clicking the information tabs related to KAD.

A possible solution: After recompiling aMule with wxgtk2.8, there have been no new memory leaks in my system (either under GNOME or fluxbox).
This task depends upon

I have the same problem with amule 10834-1. In my case amule is killed after filling all the available memory but the system correctly recovers. No special action from myself triggers the crash: I launched amule and then went away leaving the pc on, on my return amule wasn't running anymore and the usage of swap was around 600 MB.

The probable reason why aMule kills my system instead of being OOM killed is that I am using zwap compression. aMule fills all available RAM and swap.

Given the fact that currently amule is unusable and potentially leads to system instability, would it be possible to push to the repo a downgraded version (10830) linked against wxgtk2.8 (which is available in extra)?

No need to downgrade, the latest snapshot compiled against wxgtk 2.8, which is linked against gtk+ 2, works just fine. I suggested already this solution when opening this bug.

Errors here too with amule > 10830, amule complains about epoll and file descriptors....

For me 10830 with wxgtk 2.8 works fine, at least regarding the memory leak issue.

For me all versions seem to work fine with wx2.8, but with wx3 amule is always crashing.
I made an AUR package with aMule SVN compiling against wxgtk 2.8: https://aur.archlinux.org/packages/amule-wx28/
And stable aMule 2.3.1: https://aur.archlinux.org/packages/amule-stable-upnp_from_svn/
