The events can be safely disregarded.
These events are likely caused by the crash of OMSA’s "DSM Data Manager" service/process which no longer responds to periodic "heartbeat" signals sent to OMSA from the Dell Remote Access Controller (DRAC) card to determine if the operating system is still functioning properly. However, troubleshooting should still be performed to determine why the OMSA service is crashing.
However, if OMSA’s Automatic System Recovery (ASR) feature is enabled for the watchdog to issue a power action, DRAC will indeed reboot or power cycle the entire system. Therefore it is strongly recommended to leave the ASR feature disabled. Dell Engineering will address this eventing issue with OMSA 7.4 releasing in March.
