CPU memory wont drop

My CPU memory wont drop after running a Query.
The ignition gateway memory drops after running the Query.

Memory raises pulling data, then drops after it's done pulling. AS IT SHOULD and expected.

But the Memory on the CPU that the gate way resides on does not drop. even after closing out the Vision Client.
Unless I restart the gateway.

any idea why?


What kind of query? Named queries optionally perform caching, which might explain your observations. (Though off by default.)

Also, are you looking at memory usage from within Ignition's gateway performance page? Or via your gateway's OS task manager? If the latter, then you should know that java doesn't give memory back to the OS.
