Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Mark Weaver (mdw21) Assigned to: Nobody/Anonymous (nobody) Summary: netkvm.sys stops sending/receiving on Windows Server 2003 VM Initial Comment: This usually happens within an hour or two of starting the interface. It can be cured temporarily by disabling/enabling the adapter within Windows. I've run the Windows interface with log level set to 2 -- when traffic stops it still logs outgoing traffic as normal but ParaNdis_ProcessRxPath stops being logged. I suspect this is to do with the traffic content or timing as I cannot reproduce this with iperf, but only with external traffic to a website hosted on the machine. What further steps can I take to debug this issue?
