You configure a Microsoft Operations Manager (MOM) 2005 agent rule to forward an event as a Simple Network Management Protocol (SNMP) trap. However, the Snmp.exe process generates an access violation when the event is converted to an SNMP trap.
This behavior causes both the Snmp.exe process and the Momservice.exe process to stop. You also receive an error message that is similar to the following:
Additionally, an event that is similar to the following is logged in the System log:
Snmp.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created.
Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7037
Computer: Computer Name
The SNMP Service service terminated unexpectedly
This problem occurs if MOM 2005 tries to convert an event to an SNMP trap when the event description field is larger than 1024 bytes. However, this problem typically occurs when an event description field is larger than approximately 13,000 bytes.
Note The size of an event description field varies, depending on the environment. For example, when event ID 80 occurs together with an event source of DataTransformationServices, this event has a large description field.
