<DIV><FONT face=Arial size=2><SPAN class=152460712-09032010>One of our
production system routinely crashes every 10 days or so. The
error seems to be related to OpenCms' communication with MySQL, one
exception is "SQLNestedException: Cannot get a connection, pool error: Timeout
waiting for idle object" - see below for a full stack trace. I'm not sure what
action(s) to take in order to prevent this - I'm not even sure if it's
a bug or a config issue (?).</SPAN></FONT></DIV>

thread describing the same problem
