This has now been allowed to go up to 24 gigs of RAM and it's still climbing and climbing All the time using more CPU. I've killed it off Restarted it as it to do 1 simple task. It's the same thing. It's just out of control
Haha 24GB? Try 85GB for me... system crashed already crashed like 3 times today.

Well, yeah, that's actually a lot for 1 task. It doesn't matter if it's 24 gig or 85 gig, it's way too much compared to what it was before.
For me what happens is the high CPU usage when Interactive question tool is waiting for reply. It goes back to normal when I answer. I'm not noticing high memory usage though

2.0.22 is a bit better. I built a tool to fix the leaf node issue that breaks old conversations though.
