WebSphere Application Server warnings in the Process Center log file

In IBM® Business Process Manager Advanced, if the Process Designer web editor is open for a long period of time, you might notice unexpected messages in the SystemOut.log file for the Process Center. For example, you might see 0000035e, SRVE8092W, 000001b0, or SECJ0371W messages.

These WebSphere® Application Server messages are written to the SystemOut.log file for Process Center in situations where the Process Designer web editor has been running for a long period of time. They do not affect any functionality and can be safely ignored.

The following text displays with the previously mentioned error codes:

0000035e async W com.ibm.ws.webcontainer.async.ListenerHelper _invokeAsyncErrorHandling
SRVE8092W: An exception occurred invoking the async error mechanism.
000001b0 LTPAServerObj W
SECJ0371W: Validation of the LTPA token failed because the token expired

The full message text is similar to the following text:

[4/15/14 10:03:03:611 CEST] 0000035e async W
com.ibm.ws.webcontainer.async.ListenerHelper _invokeAsyncErrorHandling
SRVE8092W: An exception occurred invoking the async error mechanism.
