Symantec Messaging Gateway (SMG) 10.5.1 MTA crash while trying to deliver to a domain with hundreds of MX records.
Last Updated April 22, 2014
When attempting to send a message to a single domain with hundreds of MX records, you can possibly see a crash of the MTA service causing mailflow issues and an error similar to the following in the logs:
(err) runner: Job mta process 9775 exited, terminated on signal 11 (0x008B).
Job mta process, terminated on signal 11 (0x008B).
This is caused by a large amount (in the hundreds) of MX records within a singular domain.
This is a known issue and is addressed in SMG 10.5.2. Please update when able.
One possible workaround is to limit the number of MX records under a single domain.
