Why is my SQL Server database stuck in In Recovery mode?

SQL Server “Database stuck in In Recovery” means the engine is replaying transactions and rolling back uncommitted work. Long recovery often stems from large transactions or insufficient resources. Monitor sys.dm_exec_requests, add tempdb space, or restore from a clean backup to resolve the issue.

Typical Error Message

Database 'MyDB' is being recovered. Waiting until recovery is finished.

Explanation

What does “Database stuck in In Recovery” mean?

SQL Server runs three phases—analysis, redo, undo—whenever a database starts. If any phase hangs, the database shows “In Recovery” and rejects user connections.

Admins see this state after a crash, an unexpected shutdown, or when restoring from backup. Fixing it fast is vital because application downtime grows while recovery continues.

What Causes This Error?

Large transactions lengthen redo/undo processing. Insufficient I/O or CPU throttles recovery threads. Corrupt log files force extra work.

Limited tempdb space blocks long-running rollbacks.

How to Fix a Database Stuck in Recovery

Start by checking sys.dm_exec_requests for percent_complete. Add MAXDOP, expand tempdb, or kill other processes to give recovery room. If the log is corrupt, restore from the last good backup.

Common Scenarios and Solutions

After power loss, recovery runs automatically; wait and monitor DMV progress. If progress stalls for hours at 0 %, restore backup to a new database and switch over.

For a huge bulk load, consider applying delayed durability or batching next time.

Best Practices to Avoid This Error

Keep transaction scope small, back up logs frequently, and allocate fast SSDs for log and tempdb. Use Galaxy’s query endorsement to share optimized, short‐running scripts that reduce recovery time risk.

Related Errors and Solutions

“Database is in restoring state” appears when WITH NORECOVERY is left on. “Recovery pending” shows when the log is missing. Both need backup restores or log file fixes.

FAQs

How long should recovery take?

Duration depends on log size and hardware. Most databases recover in minutes; multi-hundred-GB logs can take hours.

Is it safe to stop SQL Server during recovery?

Stopping restarts recovery from the beginning, extending downtime. Interrupt only if restoring from backup instead.

Can I shrink the log while in recovery?

No. The database is inaccessible. Shrink after the database is online.

How does Galaxy help?

Galaxy’s AI copilot suggests smaller, efficient transactions and tracks endorsed queries, lowering the risk of long recovery events.
