There are two resolutions for the problem.
Restart the SNS$FEED_PCM.EXE application per your site-specific policies and procedures, which may involve executing a command procedure, restarting CA Console Management for OpenVMS, or by some other means such as a batch job.
If it is determined that the SNS$FEED_PCM.EXE is to no longer be used, then it will be necessary to either globally disable mailbox writing in the System Watchdog consolidator, or edit the System Watchdog consolidator profile and delete all references to the SNS_FEED_PCM mailbox set within each internal and external event class.
Perform the following steps in order to globally disable mailbox writing in the System Watchdog consolidator. Note that if further analysis of your situation is needed, you can globally disable all mailbox writing and then re-enable it later.
Execute the following DCL command:
$ SENSE WATCHDOG SHOW CONSOLIDATOR/ALL
Note the id number of the consolidator as shown in the output from the command above since it will be used in the next DCL command which identifies the consolidator for which all subsequent commands will apply:
$ SENSE WATCHDOG SET CONSOLIDATOR <id-number-recorded-from-previous-step>
Enter the System Watchdog profile editor:
$ SENSE WATCHDOG EDIT PROFILE
The following prompt will be displayed by the editor:
Next, perform the following commands while in the profile editor:
SNS$EDIT> SET CONSOLIDATOR/DISABLE=MAILBOX
The updated consolidator profile will be saved and the editor will terminate. Execute the following DCL command to force the System Watchdog consolidator to use the changes made to the profile:
$ SENSE WATCH RECONFIGURE
Once the System Watchdog consolidator has completed the reconfiguration operation it will cease to write messages to any mailbox referenced in the profile.
If you need to re-enable mailbox writing in the future, identify the consolidator by executing the first two commands in this section, enter the profile editor, and execute the following profile editor commands:
SNS$EDIT> SET CONSOLIDATOR/ENABLE=MAILBOX
Once again you must execute the "reconfigure" command shown above in order to force the consolidator to read the updated profile.
