LUA memory issue

[atharti]

Hey, like halfyear ago i notcied that when i farm mobs in public dungeon my LUA memory usage grows unendingly, usually i have about 450mb used, and i have like hunded addons. One time it reached 2 GBs (was farming for hours), well problem is not that it takes much, problem is that game start lagging. My FPS goes from stable 60 to 10 overtime, and mobs stop rendering correctly like i approach the spot use skill, already see the damage numbers but not the mobs, also other textures get scuffed. Reloading UI resets LUA memory to normal, or a relog. Its super annoying, it grows like 10mb per minute and only happening when i farm mobs in public dungeon, in blackrose prison exp runs everything is smooth for some reason.
So id like to ask you, whats happening? Is it some certain addon that works in a wrong way? Or its just how its should be? Would like to hear any advices in general or how to find that bad addon. I tried disabling massive ones like interface etc but it didnt help, general LUA memory usage goes low but it still grows.

Get Addon Selector, Turn off all your addons (except, you know, libaddonmenu and addon selector).
Does it still happen? Addon problem
Does it not still happen? Not an addon problem (it's going to be an addon problem).

From there, try turning back on and off chunks of addons until you find the one that's causing the problem.

Well its been a lot of tests.

It appeared to be ExoYs ProcSet Timer, it was the only one that was giving persistant uneding increase.
Disabled it, and started running again. Over 20 min LUA mem went from 540m to 626m, so its still growing. When i sell bag to cat, like 150 items, it went from 626m to 655m. Thing is it never goes down, only keep stacking and grow further, i have no idea at this point

Ok, just to double check. The problem arrives when you have therassian equipped and constantly farm mobs?

I will try to reproduce this problem.

(The part with only in public dungeons is weird though. Do you leave combat during your farm or are you constantly in combat?.... This wouldnbe the only difference from an addon point of view between the pb and brp.)

Also, which method do you use to determine the lua usage?
