Synopsis: Strange error in error_log State-Changed-From-To: open-analyzed State-Changed-By: marc State-Changed-When: Fri Oct 31 12:42:25 PST 1997 State-Changed-Why: Is your Apache installation on a NFS mounted patition? That is bad and a silly thing to do.
Adding a "LockFile /var/tmp/accept.lock" to your httpd.conf may fix this, assuming /var/tmp isn't NFS mounted. What the error is saying is that file locking isn't working properly on your system. This is normally caused by NFS issues.
