Hi, I'm using resin-3.1.3 on a busy site. Periodically the site
freezes. A jstack on the server shows most threads in this state:
java.lang.Thread.State: TIMED_WAITING (on object monitor)
at java.lang.Object.wait(Native Method)
at com.caucho.jca.ConnectionPool.create(ConnectionPool.java:897)

You may want to keep track of the DB pool statistics. Active versus
maximum allocation counts. If this is a connection leak you would notice
the number of active connection creeping upwards until it reaches max and
your freezing symptoms appear.
