I'm afraid I have no idea where to start looking for what the cause of this error my be. We upgraded our display and bbtest server, which is a RHEL 4 x86_64 box, to 4.2.0 at the very end of June. Since then we have the following about every ten minutes in /var/log/messages:

This system ran 4.1.2p1 for more than a year with no issues. I did an upgrade in place. No changes otherwise.
I would be very grateful for even the slightest hint on how to start looking for the problem.
Thanks very much
