Getting this error message under CSM:
MMR0004S - An error occurred during msgget(). RC: 133 Reason: EDC5133I No space left on device.

The OMVS parameters can be checked with the command:

IPCMSGNIDS may be the culprit. In reviewing the settings, check if the others seem sufficient and the Current Usage and High Water Usage are nowhere near the System Limit.
However, looking at the IPCMSGNIDS parameters, in this example, it is:
500 500 500 across the board.
So a solution could be to increase value of IPCMSGNIDS from 500 to 1000.
This limit can be set to 1000 and without recycling MSMTC, logging to Chorus again, the error messages:
MMR0004S or EDC5133I should have disappeared.
