Why you should not shrink your data files?
Shrinking of data files should be performed even more rarely, if at all.
Here’s why: data file shrink can cause *massive* index fragmentation (of the out-of-order pages kind, not the wasted-space kind) and it is very expensive (in terms of I/O, locking, transaction log generation)..
What happens if tempdb is full?
Nothing works without TEMPDB. If it grows too big, it will have a chain-reaction down through the rest of the databases, to include making them temporarily unusable. An emergency solution is always to stop and start the SQL Server services. That causes TEMPDB to rebuild at its original size.
Is full due to Active_transaction?
Transaction Log is Full Due To ACTIVE_TRANSACTION. … When this error occurs, the Transaction Log file was FULL even though a Transaction log is backed up.

Why shrinking database is bad?
The major problem with the Shrink operation is that it increases fragmentation of the database to very high value. Higher fragmentation reduces the performance of the database as reading from that particular table becomes very expensive. One of the ways to reduce the fragmentation is to rebuild index on the database.
Why tempdb is not releasing the space?
By default, the tempdb database automatically grows as space is required, because the MAXSIZE of the files is set to UNLIMITED. Therefore, tempdb can continue growing until space on the disk that contains tempdb is exhausted. … Limiting the size of tempdb may cause the database to run out of disk space.
