| Description | Lost connections to locality 0 (BASE POP4 DOWN(6) |
| Event Information | According to Microsoft: CAUSE: If your Exchange Server computer encounters a network disconnection or disruption while there are messages queued in the MTA for delivery, the MTA may fail to properly recover active associations. The time interval "n," in seconds, between the logged errors is equal to the number of seconds set in the X.400 Connector. To check this setting, open the property pages of the X.400 Connector, select the Override tab, in the Connection Retry Values frame, and read the Open Interval (sec) setting. As mail is queued to go across the WAN link, the X.400 Connector attempts to re-establish the connection every n seconds. Because the WAN connection is down, the MTA transport is not available; the MTA is logging these two events. These errors may also be caused by intermittent network problems such as a WAN connection being temporarily down. This does not necessarily indicate a problem with Exchange Server or the MTA. RESOLUTION: To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 3. |
