snort and mysql5 losing db connection

I posted this on the forums a few days ago but since there has been no replies I am asking anyone on this list for assistance. Most of my sensors are running on centos 4 without a problem using mysql and base. To start getting familiar with CentOS 5 i built a test sensor which comes with mysql 5. I compiled the latest snort 2.6.x version. What happens if I do not get any alarms is snort loses the connection and starts throwing various errors like snort[7890]: database: mysql_error: MySQL server has gone away The database is working fine. I can still connect to it. Googling, the only explanation with a possible fix I found was at http://www.uno-code.com/?q=node/81 Quoteing from the above link: "The other issue that was extremely hard to track down was when a large gap of time (usually 4-6 hours) between alerts occurred. At this time Snort states that MySQL has gone away. It appears that Snort needs a persistent connection to MySQL, and when a gap occurs that connection is lost or 'released' due to timeout, and Snort doesn't initiate a new connection to MySQL." Any ideas on how to deal with this instead of setting the wait_timeout = 10000000 in my.cnf? Another thread back in 2005 mentioned to use barnyard and not the sql connector. That is not an option for base and probably would fail with aanval users as well. I could simply go back to centos4 but that just delays the issue instead of fixing it. thanks
