Our website has thousands of hits per day. We are using the latest versions
of Mysql, Tomcat and Java. We have also been using jconnector 3.0.10. With
3.0.10, memory stayed in reasonable limits. The same happens when using any
of 3.0.x drivers. However, when we upgraded to 5, we got a serious memory
issue. Memory keeps on rising and never decreases leading to "out of
memory". Same happens with any driver after 3.1.

We also use connection pooling. On each website hit, the application gets a
connection from the pool, opens many resultsets and statements, then closes
them and returns the connection back to the pool.

Now we are stuck with jconnector 3.0.10 since with 3.1.x onwards, memory
gets out of limits.

Please advise as this is a long-time problem we have not been able to
resolve.

Thanks in advance,

Tomas.
