This rule targets catastrophic conditions that break replica set consensus: - Primary node failures followed by election timeouts where no secondary can become primary - Network partitions isolating replica set members and preventing quorum formation - Heartbeat failures and connectivity issues leading to election failures - Replica set state transitions indicating election problems | Database Problems | mongodb | High AvailabilityQuorumLeader ElectionNetworkTimeoutCrashData Loss |
