Transaction log is full for the ASP state db. How do I shrink or delete the transaction log?

The transaction log for database 'ASPState' is full due to 'ACTIVE_TRANSACTION'. My production website is down because of this error. My database is on SQL server 2014. How do I shrink or clear the transaction log Please help.

Unless the active transaction is not complete, the transaction log will not be freed up.

The 1st thing will be to figure out which is this long running transaction and either COMMIT or ROLLBACK the same.
Once done, take a log backup and you should be all set (if the database is in a Bulk-logged or FULL recovery mode).

You will want to create a maintenance schedule for the database that will do the backup of the database and logs, once you can have this setup and run successfully the transaction logs will truncate

Here is the technet article for backing up SQL 2014, please review in adjust to meet your needs.

Given that your website is down, I would go into emergency mode and first just get it running.  We can, and should and will, worry about other related issues later.

Run these commands, then report the log file total size and the % free.

USE ASPState
ALTER DATABASE ASPState SET RECOVERY SIMPLE;
CHECKPOINT
WAITFOR DELAY '00:01:00'
CHECKPOINT

EXEC sp_helpfile
DBCC SQLPERF ( LOGSPACE )


If the log file is (very) large, run this command too to see how many VLFs you have:
DBCC LOGINFO
