      Our end to end suite is reproducing this regularly. They use a single windows-64-vs2017-compile host.

      • Create a 4.3.5 Replica Set using Cloud Manager

      We're seeing backtraces during our windows testing of 4.3.5.

      The tests use a single windows-64-vs2017 host to create standalones, replica sets, and sharded clusters with the latest version of MongoDB 4.3. The crash seems to occur periodically while those items are being monitored by the Cloud Manager MongoDB Agent.
