Yes, it is. The system is a basic 1U server with a hardware RAID card and mirrored disks. I don't have any other spindles 8-/. One of my colleagues is giving me the big "I told you so", as he advocated upgrading to the hardware RAID card with a battery backed write cache which might have prevented this issue. The rest of us didn't think the extra expenditure was worth it for a Kerberos server which typically doesn't have very high performance requirements <sigh>. I guess I'm going to try purging the accesslog more frequently and seeing if that reduces the individual purge load to a low enough level that it doesn't impact service response. Thanks.
