During normal activity of CA MIM it is possible to get System Dump with error message MIM0095E MIMGR MSIERROR CODE=1120 issued by MIMEQDRV.MIMEQWNQ+045E.
Task remains active anyway.
The MIM0095E MIMGR MSIERROR CODE=1120 messages and dump occur when MIM has waited longer than 60 seconds for a user address space to process the "working ENQ" with GRS.
If MIM is not posted within 60 seconds, it generates these messages and takes an SVC dump. In most cases this is the result of a system performance issue, rather than a GRS or MIM software defect.
