One of the volumes is NFS mounted. <br>

Every couple of months or so we start getting tons of errors on the NFS mounted volume:<br>

If we pull all the data off, destroy the volume, rebuilt it, and copy our data back, all works fine; for a while.<br>
<br>
This issue does not happen on the non NFS mounted volume. I am currently assuming the issue is with NFS and how we have it configured (which to the best of my knowledge is default). <br>
<br>
Has anyone had a similar experience and be able to share some insight and knowledge on any tricks with NFS and OCFS2 volumes?<br>
<br>
Thanks in advance.<br>
