MongoDB Error 107: Lock Acquisition Failed
Description
This error indicates that a MongoDB operation failed to acquire a necessary lock on a database resource (e.g., a database, collection, or document). This usually happens due to contention with other operations, a long-running process, or a previously crashed process holding a lock.
Error Message
Lock Failed
Known Causes
4 known causesHigh Database Contention
Multiple concurrent operations are attempting to write or modify the same resource, leading to competition for locks and potential timeouts.
Prolonged Lock Hold
A previous operation is holding a necessary lock for an extended period, preventing other operations from acquiring it. This can be due to inefficient queries or slow disk I/O.
Orphaned Lock
A MongoDB process may have crashed or been improperly shut down, leaving behind an active lock that prevents new operations from proceeding.
Manual `fsyncLock` Active
The `fsyncLock` command has been manually issued, explicitly preventing all write operations and causing subsequent attempts to acquire locks to fail.
