On my TS-673A, when I perform a lot of access request to my SMB Share folder (find command via terminal in a folder with a lot of files for instance) the memory leak start and arrives to saturate 64GB of ram on my NAS!
This makes the NAS completely unusable with my MacBook. It’s simply crazy.
Just see those 2 images: in less than 10 minutes (about 7) the SMB service occupied memory goes from 1GB to 18GB!
I was just looking for some hidden files though the terminal in the smb share "find -name “filename” ". That’s it.
Please note that only 5 or 6 connection were active! for a total of 17 SMB processes! While instead this NAS is sold to support Thousands (!) of connections.
EDIT: Disabling Async I/O the memory leak disappears. So it’s pretty a basic feature that seems to be flawed by some critical bug.
