Hello,
maybe not XFS related, but it happens when XFS is present.
System is:
2x P4 Xeon
board is Intel serverboard
RAID-5 on Adaptec 2110S.
This bugs reveals only under high load (CPU), suddenly there started to be
zombie (D state) processes which had init as parent, and I was unable to do
anything else then reboot. There was no syslog/klog message. I use this
server as NFS backend to mail service and since frontend which is
delivering mail had failure on one disk in array I switched delivery to
backend and it ended with 5k+ zombie processes of kavdaemon and other
processes. This bug seem to be ACL related since there was report in czech
linux mailing list about same experience on ext3+xattr+acl. I am not able
to do destructive tests on this machine since it holds customer data, but I
am willing to cooperate since I would like to use XFS as file server file
system.
Had anyone same experience or I am alone?
O.
