  Hi Lynn,

  I was reading MCITP 70-432 ebook and came cross this section explaining why tran log won't free up:

  The database is participating in replication and the distribution database is not

  available.

  You have an open transaction.

  Database Mirroring is paused.

  The mirror database is behind the principal.

  A log scan is running.:exclamationmark:

  SQL Server cannot increase the size of a fle quickly enough.

  All of them are easy to understand but one. A log scan is running is something new to me. That's why I decided to do some digging.

  Thanks,

  Alan
