XCON: MTA Taking a Long Time to StartLast reviewed: November 10, 1997Article ID: Q163297 |
The information in this article applies to:
SUMMARYThe message transfer agent (MTA) may take a long time to start if there is a large number of DB*.DAT files in the MTADATA directory when the service is restarted. This is normal and expected behavior but is often misinterpreted as a problem. Administrators often mistakenly believe that the MTA is not responding and they complicate the issue by stopping the MTA service.
MORE INFORMATIONWhen the MTA starts, up it has to rebuild the queues in memory. If there are a lot of DAT files, this can take quite some time. One quick check you can perform is to set the MTA's logging on Field Engineering to Maximum and then monitor the 2166 and 2167 events for the number of objects in each of the queues. There is no hard and fast rule, but if you have 100,000 DAT files at startup, it is reasonable to expect the queues to grow to at least that total size before assuming the MTA is not responding.
Event ID: 2166 Source: MSExchangeMTA Category: Field Engineering Description: A call from %1 process %2 was completed, adding object %3 to queue %4. Queue %4 now contains %5 items. [%6 %7 %8 %9] (6) Event ID: 2167 Source: MSExchangeMTA Category: Field Engineering Description: A call from %1 process %2 was completed, removing object %3 from queue %4. Queue %4 now contains %5 items. [%6 %7 %8 %9] (6) |
