SNMP Queries of Very Long OIDs May Cause SNMP Service to Hang (139929)


The information in this article applies to:

  • Microsoft Windows NT Workstation 3.51
  • Microsoft Windows NT Server 3.51
This article was previously published under Q139929

SYMPTOMS

An SNMP 'get' or 'get next' request of an extremely long OID (object identifier) causes the SNMP service to stop responding (hang) on the target computer. This results in 100% CPU utilization, SNMP request time outs, and possible application errors in SNMP.EXE.

WORKAROUND

Avoid performing extremely long SNMP queries of non-existent OID's. If the SNMP agent is hung, the SNMP service can be stopped and started from the Services icon in Control Panel. This returns CPU utilization to normal.

RESOLUTION

This problem has been corrected in the latest Service Pack for Windows NT version 3.51.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
