150 maxActive setting, but we have some low usage application getting direct db
connection(out of the pool).
The interesting is that the server suddently get a lot of connections and reach the
limit and then release them.
I'm willing to change to Tomcat 7 connection pool. We are using c3pO and apache ones,
maybe that's a problem.
Thank you,
Well,
