mysql-replication

Though out of my "core" knowledge I maintain a two-way replicated MySQL database (primary and backup). It's been working fine mostly. All changes are almost instantly replicated between the two servers.

But now I've noticed something strange: I have a couple of cases where there are no replication on feb 29th. Admittedly I have not yet confirmed that all replication is lost. But all cases I've found so far have had this issue.

Not too long ago I changed timezone from UTC to CET on the backup, it has been CET on the primary all along.

Am I fixating on this because it happened on the leap day, or could there be something to it?

The servers are both CentOS 5.4 with MySQL 5.0
