[Gluster-devel] 2.5 patch 261 crashing with large rsync

User-agent: Thunderbird 2.0.0.5pre (Windows/20070702)

I have 3 large rsyncs that run in parallel that check 5tb of files. It crashes towards the end. During this glusterfs is taking 600megz of memory.

p.s. if you guys want 3 remote machines to work on let me know.

gdb bt:
