There is a core but it is from NetBSD FUSE subsystem. The trace is
not helpful but suggests an abort() call because of unexpected 
situation:

Core was generated by `perfused'.
Program terminated with signal SIGABRT, Aborted.
#0  0xbb7574b7 in _lwp_kill () from /usr/lib/libc.so.12
(gdb) bt
#0  0xbb7574b7 in _lwp_kill () from /usr/lib/libc.so.12

/var/log/messages has a hint:
Feb  8 08:43:15 nbslave7c perfused: file write grow without resize

Indeed I have this assertion in NetBSD FUSE to catch a race condition. 
I think it is the first time I see hit raised, but I am unable to 
conclude on the cause. Let us retrigger (I did it) and see if someone 
else ever hit that again. The bug is more likely in NetBSD FUSE than 
in glusterfs.
