I have been experimenting with creating custom commands to be accessible via Process Triggers and noticed that the memory does not seem to be freed up when I run 'executeCustomCommand' but does if that entire command is inlined into the process trigger itself.

I found this by writing a custom command that scans all FTP folder paths for files older that x days and flags them for deletion/further processing.

Originally the custom command was invoked from a scheduled process trigger via

system.executeCustomCommand('FolderScanner')

But I noticed after a day or so of running memory consumption would shoot up to 1.5 gb for the CompleteFTPService.exe, after which it started running out of memory.

By inlining the Custom Command (and it's dependents) into the Process Trigger the memory appears to be getting released again.

Any suggestions as to why this is happening or what techniques I should employ to avoid it?

Just to clarify, you have written a custom command in JSS, and when executed as part of the trigger it is fine, but when called via system.executeCustomCommand you get the leak?

Custom command in JSS. When inlined into the trigger it is fine,
When the trigger has a single line 'system.executeCustomCommand('FolderScanner')' it will leak.

OK, we'll take a look at the code for this - thanks.

One more piece of pertinent information.
I am only sitting on version 12.0
I have been planning on upgrading and applying the license for 12.1.4 but am beholden to internal processes (even in our development environment). so I don't have the latest version available for installation at this stage.
