Webmail or Web Workflow freezes under heavy load
Posted by John Tkaczewski on 09 July 2008 02:45 PM
If you are using FileCatalyst Webmail or Web Workflow with MySQL 4 or higher and the system during heavy usage hours becomes unstable, slow, freezes or is not responding.
Restarting Tomcat, temporarly clears these problems.

Please make the following change to MySQL configuration.

On Windows:
C:\Program Files\MySQL\MySQL Server 5.0\my.ini (use the path as configured on your server)

On Linux:

And add the following lines:


The default value of max_connections is 100 and the default value max_user_connections is 40.
