Any ideas?

You’re out of memory! Further investigation to figure out why will be necessary… Can you attach or email us your logs?

Here is the export of the logs:
logs.bin.gz (486 KB)

What version of Ignition are you running? The OPC-COM module may have had a memory leak that was just recently fixed. Upgrading to the latest would probably be a good idea.

Also, I didn’t see that error you posted anywhere in the logs…

Current Version: 7.3.3 (b570)

Strange thing about the log file … attached is a new export and a screen shot of the logs.

Also including a screen shot of the task manager showing java using 1.8 Gs of memory!

logs.bin.gz (482 KB)

Well it’s not that strange to be showing 1.8GB because you ran out of memory.

Upgrade to 7.3.7 and if the leak was on the COM module you should be all set.

Thanks Kevin, I see version 7.4.2 is the latest. Since we have Total Care upgrade protection, we will upgrade to that level.

Ah, I didn’t realize that. Yes, upgrading to 7.4.2 is a great idea :slight_smile:
