DBMS server errors include timeout, deadlock, and log file full errors. If a DBMS server error occurs during the transmission of data or the distribution of queue information, the servers increase the error count, issue a mail message to those users listed in the Mail Notification List, and retry the transaction.

DBMS server timeout means that database resources are currently unavailable and require a retry. During the retry, the server rolls back the current transaction and re-attempts the timed-out transaction.
