Seeing as you said you upgraded from 5.2 - 5.3 I would be looking at the
kernel release notes and the mysql release notes for known problems
since you did not have prior problems. I would check out the Cacti and
DNS Databases because there more realtime in nature to running on the
server than the content ones. Using the script I posted will catch the
offending query. I myself would take a hard look @ MYSQL itself. There
is a huge debate about it not being Production Ready. Last option would
be to do a yum --allow-downgrade until it's sorted out on a test
