Gluster users - Dec 2012 - NFS Server failed again over the weekend

Hi,

My nfs.log is filled with this:

[2012-12-08 16:12:56.170509] E [nfs3.c:2163:nfs3_write_resume] 0-nfs-nfsv3:

Again.

All my XenServer based VM's lost their drives.  I'm not very happy. 
This started being an issue at the beginning of November with 3.3.0, and has
continued.  It may be load based.
