Cause

The messaging engine filestore Temporary Store and Permanent Store files were deleted without deleting the log file.
Note: It is not recommended to delete the filestore files unless otherwise advised by IBM since all the messages in the filestore will be lost by performing this action.

Resolving The Problem

Delete the messaging engine filestore log file. Restart the JVM .This should create all the filestore files for the messaging engine.
