Subject RE: DBCP uses thousands of ports connecting to MySQL on XP (and f ails )

I think my max=4 and min=2, but I'll check all the settings again in case.

I had a similar problem with the DBCP / Tomcat integration (pools JNDI 
datasource connections by default). And the solution for my problem was 
quite simple - I misunderstood the resource parameters "maxActive" and 
maxActive = amount of connections that are open and put into the pool 
upon first request
... I did the mistake that I put the 30000 in maxActive instead of 
maxIdle ...

Maybe this is relevant to you. I never explicitelly used DBCP, I only 
implicitelly used the DBCP integrated with Tomcat / transparrent 
connection pooling.
