Cannot persist request GUID <GUID>, made by client application <client name> on host <host name> through connection <connection name>. Request might not be executed following a service process failure.
During a transient failure, the Integration Service could not access the $PMStorageDir to store the request for recovery.
Verify that the Integration Service can access $PMStorageDir. If the directory does not exist or cannot be written to, the request cannot be persisted.
