Threw a SiebelException: code(8236)

Lately we are getting the following error:

[ADA.448.1017] SiebelJavaOperations.testConnection() - Threw a SiebelException: code(8236), msg(OMRPC Request 130 on connection 3e4b was abandoned after 600085 ms because it timed out. (SBL-JCA-317) ). The connecton pool will now be recycled. Please retry your operation

Do any body know what exactly could be the reason behind this and how to solve this problem?

What did you do to resolve the issue ?
