SIMATIC WinCC Open Architecture Forum

Hi,

When restarting our project it fails and we get the following errors:

SEVERE, 40/pmon, Initialization of SNMP Agent (Port 4700) failed
WARNING, 54, Unexpected state, Pmon::init() failed

WinCC OA starts ok on a restart of the PC, it looks like the SNMP port is not closed on project stop?

Removing SNMP in the config file fixes the problem:

[pmon]
# allowSNMP = "Yes"

We are running 3.15 P024.

If you cannot start process please check if another program is possibly using port 4700, e.g. by using the netstat command.
Does the problem occur on several machines or only at one system?

Hi Leopold,

It was on two servers, the WCCILpmon.exe proces was using the port. But when I tested it today the same problem was not repeated!

In any case, we will remove SNMP on the pmon as it isn't required.

Thanks for your reply,
Ellen
