Regarding SDL TM Service Host

Hello!

I was wondering if anyone ever encountered this issue.
At some point during the day, SDL TM service host will stat consuming so much memory out of nowhere. It always happen at 10H30 untill 11h45 then 14:45 until 16:00. In studio, context search and memory editing/consulting becomes very slow. Confirming segments also takes around 15 to 30 seconds.

Basically, the service will start using more and more memory until it reaches a certain threshold (30% to 40%) and then will stay that way for a hour. I usually restart all services but it doesn't change anything; it goes back up after 2 or 3 minutes. After one hour it goes back down to normal conditions and everything becomes super fast.

I've checked the background tasks in the UI and everything is normal. Nothing is queued regarding TM tasks and we do not use the online editor.


I would like to know what is the service's utility, so I can check if there is a fault somewhere.
