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

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.
