Hi everyone!

For a three days in a row we have the same problem: Everything works fine (tags are fine, no red tags), but operators can’t change setpoints to HVACs. After rebooting the server with Ignition everything works fine.

Today in the morning I see an error:

I attached log-file from console. Maybe it will help.

On the forum I found the following solutions of the problem:

1. Reinstall x86 java and Ignition to x64 java and Ignition
2. Upgrade to version with fixed COM-module’s bug (blocked threads).

What you can advise?

I’m sorry I didn’t look at threads in console before rebooting the server. I’ll do this at another time when the scada will not work properly.

P.S. Ignition is x32; MaxHeapSize is 1500 MB (file ignition.conf)

Hi everyone!

New day and the same problem. Now I see the same error (“Not enough quota…”) and one thread is blocked.

I have attached files from console.

There have been quite a few changes that were made to the OPC-COM module for 7.6.4 which was just released today. Could you try updating and let me know if you run into the same problems?
