Explanation

In past cases this error has indicated that the SQL transaction log for the project database had reached its maximum file size or there was no more disk space to allow the transaction log to grow. If this is the cause, the transaction log needs to be truncated. Contact the database administrator.

Steps to Resolve

One possible solution is to backup the database. If the "truncate log on checkpoint" option is enabled, backing up the database using SQL Server Management Studio or other means should truncate the transaction log. The "truncate log on checkpoint" option is on by default if the recovery model is set to "Simple" for the database.

"Note: The transaction logs are very important to maintain the transactional integrity of the database. Therefore, you must not delete the transaction log files even after you make a backup of your database and the transaction logs."
