[opencms-dev] OpenCms crashes, Timeout waiting for idle object / Exception Processing ErrorPage

Wed Feb 18 18:39:02 CET 2009

For a while now OpenCms keeps crashing every day. What happens is that the
maximum number of connections
is reached (db.pool.default.maxActive) and then no further connections are
possible. I get a lot of 
NoSuchElementException from all directions (see bottom for one example).
After a restart everything works fine again 
for a while. The connections are all to the opencms-database and are not
coming from my code, I'm certain.
The load of the page is not overwhelmingly high.

Configuration: Debian 4.0,  MySql 5.0.51a, Apache 2.2.3, Tomcat 6.0.18.

There is only one noticable Error occuring (you can find the message below)
which still should not lead to the rising of connections, I think.

Can anyone help me?
Thank you and greetings
Marc Johnen
