(C3750-HBOOT-M) Version 12.2(25r)SEE4, its my version
This is the bootstrap version. Post the complete output to the command "sh version".
This 'VMATM' process mainly takes care of the removing the
addresses learnt on an interface when the interface goes down.
The HRPC process apparently handles remote procedure calls on a 3750 stack
What is that you are seeing in the logs?
Did you ever find a fix for this? I've just hit exactly the same symptoms. High CPU with VMATM Callback at the top and "HLFM-6-ADDR_SYNC" messages in the log.
I'm running this c3750-ipbasek9-mz.122-25.SEE2 and probably long over due an upgrade.
