Is it a memory leak if you don't see it?
Got the Win11 2H/24 Upgrade and started to have a terrible memory leak.... but only when I was not using my machine. After days of looking at Task Manager, Resource Monitor, PoolMon, and RamMap I figured what was going on. The memory leak would only start some minutes of idle activity and would stop leaking as soon as you moved the mouse, at which point the cycle would continue.
svchost.exe (defragsvc) : This puppy gets run by a scheduler in the background to "defrag" your drives when the PC is not busy... but something in 2H/24 seems to leak (or not release) memory until the entire process has concluded... which just does not happen on an 80TB pool as you run out of memory first, reboot, and the cycle starts again. I was losing about 1gb per minute.
Turns out, under "Optimize Drives" you can specify what drives, and on what schedule, the drives will be defraged. I've now excluded my spinning rust Media Pool drives (rest are solid state) and at which point all the missing memory magically reappeared. The oddest thing is I'm now manually running defrag on one of the drives as a test and there is no memory leak / memory consumption like I was seeing. So not svchost.exe (defragsvc) itself (or the underlying ntfs/refs processes)... maybe what ever is scheduling the defrag. Who knows. I'm over it.
