      Description

      We recently added a new hidden secondary to one of our many clusters. The cluster, while on version 3.4.10, is running in featureCompatabilityMode: 3.2. After initial sync, while rebuilding numerous indexes, the server crashed while attempting to create what appears to have been its 65th index.

      I suspect a fatal exception here is not ideal. I'm also curious how our other systems are still alive, while on the same version.
