Final note:
Sawtooth patterns in java memory usage are normal, usually. You have a situation where a tiny sawtooth turns into a large sawtooth, that persists after the load is presumably finished. That part is unusual. Memory eventually filling up and crashing is also unusual.
Thanks for your help, very useful.
Hi all, I'm new here.
I created a project by following the Ignition course and I realize that the Zulu Platform x64 Architecture service takes a lot of RAM even if I have no applications open or projects in progress. I don't really understand what's going on.
That just how java works. A JVM is given initial and max memory settings at startup, and never gives back to the OS. (Heap is recycled within the JVM, not to and from the OS.)
Also, Ignition gateways run as a service in the OS--no user interface is displayed from the service itself.
