Yesterday we had a big issue with the ignition gateway running out of memory, causing a lot of HDD swapping, which dropped out other important services on the server.
After some investigation, it looks a lot like a memory leak to me.
We’re running some other projects on 7.9 without problems. So it must be something with the modules or the scripts we use for this specific project.
It’s the first time we use the web-browser module, with a custom-made web page. A memory leak in a web-page is also possible ofc, but that should show up as a client memory leak I guess, not on the server. Perhaps it’s the web-browser module itself?
Meanwhile we’ve increased the allocated memory, so it should at least hold out a little longer.
Also notice the resemblance to this post: https://inductiveautomation.com/forum/viewtopic.php?f=72&t=16439&p=60085, though we don’t appear to get those big drops (and I still don’t get what those big drops are, the regular small spikes are normal Java garbage collection, but I never heard about a garbage collection happening once every 6 hours).
