[opencms-dev] MySQLNonTransientConnectionException- toomany connections

Hi Paul! 

Still having fun? :)  Regarding the ULIMIT this is a very important setting.
Check the limit for the tomcat user. If you are using tomcat6:

sudo su tomcat6
ulimit

The best way to set tomcat limits are directly on the init.d as I mention.
At least for UBUNTU and RED HAT (we confirmed a bug ignoring this setting on
those distros).

Regards
Hernán.
