Hi,
We're using jBoss 3.2.2 and are encountering:
No ManagedConnections available within configured blocking timeout ( 5000 [ms] ); -
nested throwable: (javax.resource.ResourceException: No ManagedConnections available
within configured blocking timeout ( 5000 [ms] ))
I have a small test case where we do a sleep in our ejb to cause the
transaction to time out (I set it to 30 seconds). If I run this case enough
the AvailableConnectionCount from the
org.jboss.resource.connectionmanager.JBossManagedConnectionPool
mbean in the jmx-console reports 0 connections available.
The code to fetch a connection is wrapped with the try...finally block
to ensure that the connection is released. However, with the sleep we
never fetch a connection. The exception trace is:
18:13:01,647 INFO [TxConnectionManager] Could not enlist XAResource!
javax.transaction.RollbackException: Already marked for rollback

nManagerProxy.allocateConnection(BaseConnectionManager2.java:814)
at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(Wrapp
erDataSource.java:102)
I can reset the AvailableConnectionCount back to its maximum by
invoking flush() from the jmx-console; however this is not practical.
It appears that transactions that time out do not release their connections
back to the pool. Has this issue been resolved in a newer release?
Thanks!!
Albert
