Hi,
we have a server that seems to be sensitive to vzquotas. I'm not sure if there is a drive issue, or controller issue (Perc 6/i) or whether its the vzquota software but it seems the instability we've been experiencing on our servers could be related to vzquota. When we turn quotas off the server seems more stable. Here are some examples of what we're seeing in our logs:

The log goes on and on, many similar such entries repeated.

Anyone seen this before, know of a fix? Thanks
