We have a MongoDB cluster setup with following configuration
- 1 primary
- 2 secondaries (1 connected to clients but not used for reads, other one not connected to clients at all)
- 1 arbiter
Throughput pattern is write heavy with comparatively lesser number of reads.
A few days back, our primary crashed out of nowhere. It emitted the following traceback,
