This broker is now in slave mode waiting a lock to be acquired

Cause

Unable to update ../messageService/BrokerData directory

Resolution

Allow read/write access to ../instance/messageService and subdirectories, including the ./brokerData directory

Check the userid that the ZMSSTART task is running under to ensure proper group access is permitted.
