samba - Oct 2024 - Samba AD-DC memory loss

Hello

I am running a Samba 4.18.6-Debian AD-DC on a Debian 11 VM with a
replication
on another identical server. I always have about the same number of tasks
but the
consumed memory always increases over time without ever decreasing.
Do you have any ideas to explain and avoid this memory loss?

Main PID: 350 (samba) Tasks: 61 (limit: 4631) Memory: 617.6M CPU: 4h 46min

This is not expected (but, being software, not entire unexpected either).

`ps faux` might show what processes are using the memory, which still 
leaves you a long way from working out what is wrong.
