* PROBLEM DESCRIPTION: Connections are ocasionally not         *
*                      discarded when unused or aged timeout   *

* RECOMMENDATION:                                              *
****************************************************************
Connections are not discarded when unused or aged timeout
expires because the pool maintenance thread is occasionally not
started.  This may lead to a number of inactive database
threads. Depending on  specific configurations it may also
cause the following error:
J2CA0056I: The Connection Manager received a fatal connection
error from the Resource Adaptor
when a firewall or socket timeout expires causing physical
connection to be closed.

Once this problem occurs, it will not correct itself.
Problem conclusion
Corrected a timing issue that may cause that the connection
maintenance thread is not started because it is assumed that
is has already been started.

Level (Fix Pack) 6.0.2.27 of WebSphere Application Server V6.0.1
