Error 9002. The transaction log for database is full due to 'NOTHING'
NOTHING is basically a 'Not any of the other reasons' status. Other Log Full status values I've seen are: LOG_BACKUP, REPLICATION, and CHECKPOINT.

As to the cause, check the log file max size &amp; growth properties. Then compare them to the available disk free space. The log file may have reached the Max size, or the disk may not have enough free space to accommodate the next growth interval/amount.
