At approximately the same time every morning, the SystemOut.log records the following exception:
ASYN9999E: Unexpected Exception Occurred: com.ibm.websphere.asynchbeans.SerialDeserialException: Exception while deserializing a saved service. Service=security. Unable to deserialize the Subjects in this Context, cause: Validation of LTPA token failed due to invalid keys or token type.
The AsyncBean in the scheduler table has LTPA token that was signed by the outdated LTPA key
Resolving the problem
The scheduler table needs to be cleaned up via the ConfigEngine script 'action-clean-scheduled-tasks'.
- For Windows: ConfigEngine.bat action-clean-scheduled-tasks -DWasPassword=<WasAdminPassword>
- For UNIX: ./ConfigEngine.sh action-clean-scheduled-tasks -DWasPassword=<WasAdminPassword>
