[Gluster-devel] constant "failed to submit message" to rpc-transport

[Michael Brown]

After a bit of load, I constantly find my gluster server getting into a
state where it seems to be unable to reply to NFS RPCs:

[2013-05-05 01:31:16.421507] E [rpcsvc.c:1080:rpcsvc_submit_generic] 0-rpc-service: failed to submit message (XID: 0x3705786983x, Program: NFS3, ProgVers: 3, Proc: 6) to rpc-transport (socket.nfs-server)
[2013-05-05 01:31:16.421528] E [nfs3.c:627:nfs3svc_submit_vector_reply] 0-nfs-nfsv3: Reply submission failed

http://pastie.org/7803022

Any idea what to do about it?

The NFS daemon also gets rather large - I suspect it's storing up data
for all these RPCs:
  PID USER      PRI  NI  VIRT   RES   SHR S CPU% MEM%   TIME+  Command
30674 root       20   0 37.6G 37.3G  2288 R 99.0 29.6  5:29.88
/usr/local/glusterfs/sbin/glusterfs

I'm running 3.3.1 with a few patches:

Workload is usually Oracle DNFS.
