Question : ExchangeMTA Event ID 2219

Every couple of weeks our exchange server becomse unreachable for a few minutes.  In the application event log, I see event ID 2219 followed by serveral 2206 followed by 2207.  Shortly after the Exchange IS restarts and then everything is okay.

What is causing this?

Answer : ExchangeMTA Event ID 2219

Which version of Exchange are you running.

These errors are normally generated when the server runs an MTACheck after the server / services have been restarted following an abnormal restart

Post back with the version, can you also check if there is anything in the eventlog showing what is restarting services / restarting the server?
