Can someone help me understand the JDBC connections graph. Our graph
is showing JDBC connections continually rise, but never seem to come
back down. Is this normal behavior or is that a good indicator of a
leak?

Hello,
Which connection pool are you using? I have seen a similar problem using Tomcat 7's pool. On my system the 'used jdbc connections' always rises (up to 100K or more). It's not possible for my app to leak real connections at this rate, else it would fail long before the count got that high.
Interested to know if you see the same thing.
Thanks,
Colin

We use C3P0. It was leaking about the same. We found the issue and
fixed it now.
