MongoDB Error 41: Resource In Use
Description
This error indicates that MongoDB attempted to access a file (such as a data file, journal file, or lock file) that is currently open or locked by another process or another MongoDB instance. It typically occurs during startup, shutdown, or when performing operations that require exclusive file access to critical database files.
Error Message
File Already Open
Known Causes
3 known causesAnother MongoDB Instance Active
A different MongoDB `mongod` process is already running and holding locks on the necessary data files, preventing a new instance from starting or accessing the files.
External Process File Lock
An external application, such as a backup utility, antivirus software, or a file system utility, is currently holding an exclusive lock on MongoDB's data or journal files.
Stale Lock File Present
A previous unclean shutdown of MongoDB may have left behind a stale `mongod.lock` file, which incorrectly indicates that the database is still running and its files are in use.
