I Guess I am posting too many issues in the past 2 or three days. Any help in fixing these issues would be highly appreciated.

Well, this is one in the Queue of issues.
Application configuration : Contains EJBs(mainly MDBs) deployed on OC4J, using JDK 1.4 with Tamino 4.1.1.
Follwoing is the error when I run my application for concurrency loads.

two scenarios are possible:

1. An _XQL request was issued with _LOCKWAIT=no and _ISOLATION=shared/protected. At least one of the requested documents was locked by another user, therefore the lock could not be granted immediately.

In this case you have to check the architecture of your application for concurrency loads.

2. If your application shares connections between EJBeans and the connection sharing daoes not work properly.

Please contact the Tamino Support. We’ll need more information:
1. the architecture of your application.
2. Deeper stacktrace
3. The trace output of the Tamino Connector
