Environment:
ProLiant DL360 Gen10, 48 cores, 128GB memory, Centos 8

Description

We have a primary with 2 replicas and have seen a crash where both replicas crash almost simultaneously at the same query. At other times during the day the same query has had no problems and unfortunately we have not managed to replicate this either.
So far we have seen exactly the same behaviour only once more two weeks ago where a very similar query crashed both replication servers.
In both cases there was a bulk import running on the primary server that got replicated to the crashing replicas, but on a different schema and table that is requested in the query.
