I think that it's unlikely to be relevant.

In the case of this time, /bin/dash is apparently the cause of the
fork bomb by a bug in handling PS4 shell variable from the result of
testing on the github issue 734.

In the case of ClusterMon you mentioned, crm_mon is the one forking
repeatedly, not the ClusterMon shell script, not invoked via /bin/dash
either.
