Hello,  
I am getting this error and can not trace it, I am not sure how to resolve it either.  
Any idea where to look?

I'm seeing this right now and ours seems to correlate with install of Ignition v8.1.33 and failure of the DNP3 driver to read data from any devices.

I'm seeing this on v8.1.39, it started early yesterday morning. The source is a UDT instance value change script that gets called every second. The peculiar thing is the instance has been functioning properly for more than six months. Restarting the gateway cleared the errors.
