HI Our System is a SNMP Managed System.Socket listening at 161 port. When i do a normal Get-set operation its works very fine. No problem with it. Packetyzer Trace: But when my system receive a NBNS request packet in port 137. The Switch repond saying Destination Unreachable ( since the port is not open ). But Henceforth when i do a SNMP get on my system My system gets hanged. This happen exactly With the response to SNMP get-Reuest as soon as the system send the SNMP response message out through Socket using Sendto function my system gets hanged. what could be the problem. We are stuck with this problem for long. Plz Help needed. I am Attaching the NBNS packet.

Your subject mentions "tNetTask" and you refer to a "switch" somewhere in the message body. My guess is, your "system" is an ethernet switch that is running VxWorks. At the most, I can suggest that you try comp.os.vxworks and provide *relevant* information related to your "system" being suspended. -ls <-- Snipped the packet dump --> | |||||||||||||
