Gateway connection dropping out

Ignition
,
1

Our connection to the gateway keeps temporarily dropping out.

In the designer, at the lower right corner, notifications that the gateway connection is lost, then restored are popping up about once a minute, sometimes more.

I am not seeing anything in the logs indicating a problem and the memory usage and cpu trend are well within normal.

Currently, the only client connected is running on the gateway itself. The connection issue is causing the client to briefly disconnect as well.

Where would I begin to troubleshoot this issue?

Thank you

Do you have aggressive anti-virus running on the gateway?

Is anything showing up in the gateway logs?

No anti-virus, it is an industrial PC that came bare bones Windows 10. Only have necessary software installed.

Nothing is showing up in the logs accessible through the gateway page in a browser. Is there another log file I can check?

The wrapper.log file in the install folder might have a bit more.

What does the Status => Performance page show?

You have a 10-second stall showing. Something is disrupting Ignition. You may need IA support looking over your shoulder, as there's nothing else unusual there.

(Are you trying to run the database in the same hardware?)

wrapper.log is showing the same information as the log in the gateway page. Nothing seems to be related to the gateway connection.

I see. Yes, we have a MySQL server running on the same hardware.

We've used this setup on other machines and did not see this issue. I must've set something up differently here.

It's a negative 10 second stall, which means it was a clock correction.

Eww! Missed that. One of the reasons I hate Windows--time jumps. (Linux slews its clock to gradually sync up to external time sources.)

Code shouldn't be susceptible to time jumps, but often is.

Consider changing operating systems.

I would absolutely switch to Linux, but supposing that changing the OS is not an option (there is other software that runs that is not Linux compatible) how would I begin to debug this problem?

12

First, I would look back in the logs to see if similar time jumps are present whenever the disconnections happen. If so, two actions to take short of OS replacement:

  • Fix your facility's time synchronization infrastructure, and

  • File a support ticket with IA.

If not, then I'd still file a support ticket to let IA look over your shoulder, for obvious problems that don't translate very well to this forum.

Will do! Thank you
