My amule (full gui version, not the separate frontend or backend) crashed in the same place. Although this has nothing to do with hibernation for me.
It may be a race condition, because I did have some serious disk activity. (I accidentally held down Print Screen for several seconds while running GNOME, which started a flood of gnome-print-screen processes. My machine didn't start thrashing, since I have plenty of RAM, but it got pretty bogged down for a while. I run nice ionice -n6 amule, so amule probably ended up waiting for a while. I don't know for sure if amule crashed right while I was doing that, since that load spike happened for maybe a couple minutes in a maybe 2 hour window where I didn't check on amule.
(amule:21943): GLib-WARNING **: /build/buildd/glib2.0-2.18.2/glib/giounix.c:400Error while getting flags for FD: Bad file descriptor (9)
FD 9 is the control socket: ll /proc/.../fd, and lsof:
lrwx------ 1 peter-unpriv peter 64 2008-11-09 04:51 /proc/21943/fd/9 -> socket:[9028141]
amule 21943 peter-unpriv 9u IPv4 9028141 TCP localhost:4712 (LISTEN)
I use amule v2.2.2 (--enable-debug, with wxGTK 2.8.9 both built with -D__WXDEBUG__), on AMD64 Ubuntu Intrepid (gcc 4.3) on a dual-core Intel CPU. I run amule inside a Xvnc.
amule was just sitting there, not iconified, showing the transfers window. There were 39 incomplete downloads, 7 of those in the stopped state, and a few others that will probably never find any sources. (none of the downloads have more than a few sources, and are coming in _very_ slowly.) I'm sharing ~2800 files.
I didn't connect to port 4712 on purpose, and I'd be very surprised if anything else I was doing on the machine connected to localhost:4712. I was browsing the web with firefox for some of the time window amule crashed in, so it's _possible_ something might have had a localhost:4712 URL! I'm pretty confident my network is secure, and I run amule on a machine in my LAN with ports tcp:14662, udp:14665, and udp:14672 forwarded from my Linux firewall/server machine.
