I'm seeing similar problems with 2.0.1 -- any log entries?  I get a lot 
of these in glusterfs.log when mine hangs:

[2009-06-11 05:10:51] E [client-protocol.c:292:call_bail] zircon: 
bailing out frame STATFS(15) frame sent = 2009-06-11 04:40:50.

My setup is very close to yours -- using replicate, iocache, readahead, 
and writebehind on the client and iothreads on the servers.  The thread 
below sounds like my problem, but I don't have autoscaling (explicitly) 
turned on:

...so I'm wondering if it could be something else.
