Hello,
On a VM guest (running under KVM) with CentOS 5.8, I yesterday strangely
got the following (see below).
The server runs apache/php/squirrelmail/postfix/dovecot/openldap and it
is a production server.
Do you advise to do some particular file system checks or other
settings? Any other advice?
Such errors have not appeared in the past.
Thanks,
Nick
