Reliability of MySQL of FW Analyzer

Hello,

Like to enquire about the reliability of the MySQL DB that runs in FW Analyzer.

I'm evaluating FA Analyzer for 5 days. 2 Netscreen 25 firewalls & 1 Sonicwall IPS Pro3060 send their logs in Webtrends format to the FA. Today the FW Analyzer stopped working. I was not able to start the FA service again.

Every unsuccessful attempt to start the FW Analyzer service will result in the event log having this message:
There were 5 failed launches in a row, each lasting less than 300 seconds. Giving up.

With this prompt:
- Unable to start MySQL server on port 33336. Please free the port.

Finally I'm able to start the sevice by first running the stopdb.bat in command prompt.

I would like to find out the reliability of MySQL in FW Analyzer, and the possibility of using a SQL Server instance for better reliability.

Pls advice.
Thanks.
