Last updated on JUNE 25, 2018

Applies to:

Oracle Communications Converged Application Server - Version 5.0.0 and later
Information in this document applies to any platform.

Goal

The following error is thrown from some engine tier nodes:

com.bea.wcp.sip.engine.server.UnableToLockException: Could not lock call state even after waiting for more than 5000 ms
at com.bea.wcp.sip.engine.server.CallStateManager.enter(CallStateManager.java:220)

Do we need to do explicit lock/unlocking of a session or suchlike? Or will the OCCAS container take care of all this?
