Hi guys,

Hope you can help me.

I'm running a UCCE platform in version 7.5(9) and I'm having problems with the PG (TCP connection to VRU has been broken) which is located at the remote site.

PIM dumplog at the PG side log shows:

You might think is a physical layer problem but Telecom got no errors on the switch interface nor any kind of disconnection on the WAN link. Antivirus is disabled, NIC offload features are set off as well as TCPChimney, RSS and TCPA.

Any other suggestion or troubleshooting idea?

Thanks in advance

we had similar kind of problem where pim was getting disconnected with CVP.

and at the end we found that it was driver issue(NIC) on windows server 2003. below is the link covering issue fixed by MS.
