Hello All,
We have an AIM*OPC server installed on an AW running Win 2003 Server. The OPC
server is working (will return data, no errors). We have an OSI PI data
collector running. It will connect to and get data from I/A via the OPC link.
This will work for several days, but then the AW becomes so unresponsive, it
must be rebooted. After a reboot the problem goes away for a day or two, and
then returns.
Running the netstat command shows the following
TCP SRVONE:4997 SRVTWO:45678 CLOSE_WAIT 612
AIM AT OPC Server
[Aimopcsvr.exe]
TCP SRVONE:4998 SRVTWO:45678 CLOSE_WAIT 612
AIM AT OPC Server
[Aimopcsvr.exe]
...
We have these going from SRVONE to ALL of the other AWs, not just SRVTWO. It
looks like some kind of broadcast message to the other AWs.
Does anyone know what would cause this, and how we should correct it.
Thanks,
David Johnson
