MongoDBWiredTigerMetadataCorruptionCrash LoopStartup Failure

Description

Detects MongoDB failures where the server enters a crash loop due to corrupted WiredTiger metadata.\nThis prevents startup and often requires manual repair or restoration from backups.\n

Mitigation

Prevent unclean shutdowns, monitor disk and filesystem health, run regular backups.\nIf corruption occurs, attempt recovery with mongod --repair, or restore from a known good backup.\n
