Hi,

Mongodb version 4.2.20 is being used.
replicaset with 3 replicas, with readPreference=primary
During load testing, the primary node mongodb had crashed with following error and it never came back.
there was no core file generated
mongod service had to be manually restarted
disk utilization was at 40%

 

Any leads about why it was aborted would help and how to analyze such issues?
