Issue:
  • data_engine probe periodically stops and in data_engine.log I see
ADO_Database::ExecuteSP com error for [Microsoft OLE DB Provider for SQL Server] The transaction log for database 'CA_UIM' is full due to 'ACTIVE_BACKUP_OR_RESTORE'.

 
Cause:
  • SQL has run out of space for transaction log and therefore the data_engine cannot write any data to db.
Resolution:
  • Provide more space either by increasing size of transaction log or by truncating it.
  • Should also check that autogrow is not at default of 1MB for data files and 10% for transaction log, Increase both to a fixed MB value (e.g. 100MB) to ensure that the DB can always keep up with demand
