M204.0585  Shared dasd enq list overlaid for file fileName token

An entry in the list of shared DASD enqueueing entries has been overlaid. Model 204 keeps a data structure called the shared DASD enqueue list to handle sharing of Model 204 files across multiple CPUs. This message will appear if the last job to close the file cannot find its original entry in the list. This may occur if there were two jobs with the same job and step name, or if the system operator used the ENQCTL command to modify the shared DASD enqueue list.

System manager response: Make sure that all Model 204 jobs have unique job and step names and that the system operators make careful use of the ENQCTL command.

Operator response: Notify the system manager.
