[Gluster-devel] memory leaks

Attached are my present spec files for both servers (which are also my
clients); both machines use the same files.
To trigger the memory leak, all I need to do is a "dd if=/phys/blah0
of=/dev/null bs=1M", where /phys/blah0 was created with "dd if=/dev/zero
of=/phys/blah0 bs=10M count=1024". It seems fine for a moment, but then
glusterfs starts growing and growing until it can't claim any more RAM
and becomes useless (can't ls the mountpoint, dd doesn't complete)...
Both machines are running Ubuntu Edgy + Fuse 2.6.3.
Thanks,
Brent
