I believe this crash happened because the number of file descriptors open in the process was above 1024, the limit for the select() system call that is used in the underlying wxWidgets toolkit. I suggest using 'ulimit -n 1023' (or pick a smaller number) in whatever shell is used to start amule.

Ideally, amule would either manage its file descriptors more carefully or amule would switch to using the epoll API for socket readiness notification, either via a different wxWidgets API (if one is available) or managing its own sockets.

I suggest filing a bug with upstream amule developers.

Thanks for reporting this issue to Ubuntu.
