RESOLVED: Resource exhaustion on the Mail Relay Service
Vendor support has corrected the problem, and the unit is back online. The Mail Relay Service is back in full production as of 6:08 PM.
Vendor support has been engaged. They have identified why the affected unit is not functioning, and are working to correct the problem. There is no ETA at this point, but the vendor will call back with a status update no later than 6:40 PM this evening.
Although the Mail Relay Service is in a degraded state since it is operating on only one server, a single server is capable of handling the load under normal circumstances. With the immediate cause of the problem (the 1000 copies of a 25 MB message), now passed, the single unit is carrying the load without a problem. There are no mail delays other than the 3400 messages stuck in the queue on the nonfunctional unit.
The cause of the resource exhaustion has been identified. One of the two servers has recovered, but the other is not processing its mail queue. ITS Systems staff are engaging vendor tech support. We are running only on the recovered server, so customers should no longer be experiencing mail delays. However, about 3400 messages are stuck on the nonfunctional server.
The Mail Relay Service (aka relay.mail.utexas.edu and outbound.mail.utexas.edu) is experiencing a resource exhaustion problem. One of the two servers implementing this service is not responding, and the other is under heavy load but still functioning. Customers may experience mail delays. ITS Systems staff are investigating.
