we run about 60 RHEL5 VMs that are AFS clients.  AFS is generally NOT =
heavily used on these VMs but it is used some.  We've never had any =
issues like you describe, Steve.

The servers are only holding Read Only volumes. On each fileserver there =

removing the volumes.

move them to RHEL (maybe in Vmware) in the future once a backup solution =
is ready. We have really never had any problems with these Linux VMware =
AFS servers the whole time they have been running. (since July 2008) =
They've been working pretty good for us.
