Ignition Gateway crashed

Ignition crashed with the following errors
Version: 8.1.35
Using Perspective

Can someone tell me what could be the reason for this failure?
I'm reading real-time data from an external server using Http Rest calls and suddenly that stopped working and server got frozen.
I had to restart the server to get it going again.

Not with just a screen shot. Please find your wrapper.log file in your install folder and grab the lines from about ten minutes before the crash to just after the restart. If very large, save to a separate file and upload separately. If not to large, paste into a comment using the "Preformatted text" button to keep it neat.

In the future, also screenshot the "Performance" page on the gateway, that shows the CPU and memory utilization at that time.

wrapper.log (2.9 MB)
Here is the wrapper.log file.
Ignition gateway failed on 20 April 11:09 PM

How can we go back in time and check the utilization details? historical performance data saved somewhere?

You can't, unless you've set up historization of the [System] tags that have that information.

Which is why I said "In the future".

Meanwhile, if you had click the "plus" icon on those "unexpected exception" log entries, you would have seen these details:

You gateway ran out of heap memory. Whatever you are doing with that external API likely needs more memory.

Or some Perspective user tried to graph a large time range at precisely the same time that the API calls were attempted.

Anyways, your gateway needs more ram allowed (in ignition.conf), which may mean the physical machine needs more ram.

This is interesting because it means one of his project resources is 11MB... I wonder what it is and how many others like it exist.

Thank you for the reply.
I've it set to max heap size 4GB

Is there a quick way to identify them like the long db queries. ?

Set your init memory to the same value that way java claims it all at the beginning.

Best thing you can do for a scripts etc... is to use the Java nanotime and log custom script execution time. Or log when it goes above a certain length of time.

Also be careful where you are calling the api calls. Some areas are more tolerant to long running scripts than others.

Hmm, I don't think there's anything in Ignition to find large resources.

If your Gateway is running on Linux you could change into the projects directory and run something like du -h * | sort -h and look at the larger entries.

edit: probably needs a little tweaking to find the large resources and not just the large projects.

any of these windows actions do affect the Ignition service?
