Hi,

We are facing a problem with database connections in JBoss. we are using mysql as the db server..

During peak loads, getting the following exception..

Caused by: javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 5000 [ms] )
at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.getConnection(InternalManagedConnectionPool.java:262)|
at org.jboss.resource.connectionmanager.JBossManagedConnectionPool$BasePool.getConnection(JBossManagedConnectionPool.java:496)|
at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManagedConnection(BaseConnectionManager2.java:425)|
at org.jboss.resource.connectionmanager.TxConnectionManager.getManagedConnection(TxConnectionManager.java:318)|
at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:477)|
at org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:814)|
at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:102)|

Could be because the connections are not being closed in all the places in the application? or is there any other reason to it..??
Any way to check this ??

thanks
