Hi Paul, I have raised a support ticket for this already (#7733). I have included both the wrapper log and thread dump while the gateway was having issues.
The Ignition installation had been running for approximately 6 months without any issues.
It is running on an Advantech Embedded IPC which is running Windows 10 Enterprise 2016 LTSB. The machine did not reboot or power down as far as I can tell from the Windows Event Logs. It does not have internet access and it was therefore not installing Windows updates.
