Hi,
Since upgrading to "2.6.18-194" I am getting odd messages in the logs.
Such as;
sraid3 kernel INFO task pdflush 259 blocked for more than 120 seconds.
The output from
> grep '120 seconds' /var/log/messages | tr : ' ' | awk '{print $10}' | sort | uniq -c
6 nfsd
4 pdflush
This is from an NFS server that since the upgrade has been flakey. I have
an identical server running "2.6.18-164.11.1" and no such messages are
seen.
is anyone else seeing this and/or know what is going on?
Steve
The messages appear as follows.
