M204.1252  Unable to stop subsystem subsysName

If this message is preceded by the following message, then the user attempted to stop a suspended subsystem:


The subsystem must be resumed before the STOP command can be issued. Otherwise, the error occurred for one of the following reasons.

During STOP SUBSYSTEM command processing, Model 204 opens all subsystem files. An error occurred while Model 204 was attempting to open the files, and Model 204 cannot properly stop the subsystem. The error may have occurred for one of the following reasons:

  • The SCLASS associated with the user could not be found in CCASYS.
  • The SCLASS record associated with the user was being updated at the time the STOP SUBSYSTEM command was issued.
  • An error occurred while Model 204 was opening a subsystem file.

Response: The problems may be due to a record enqueueing conflict. Try again later. If the problem persists, notify the system manager.

System manager response: Check to make sure the SCLASS record for the user exists in CCASYS. Check to make sure that the subsystem files exist for the Online Model 204.
