I've checked the sizeof the main structure used to represent a mount unit (struct Mount) and it's 1488 bytes. There're probably more structures involve during the process but the memory consumption per mount seem too high in your case. I tried to reproduce but the memory consumption was only about 12.5MB (for 1000 mounts) in my case... Regarding the release of memory, I checked that systemd frees the allocated structures when unmounting. I also verified there's no memleak by mounting/unmouting the same directory in an infinite loop and the mem consumption stood stable. I don't know why the kernel reports the old memory consumption but you can easily see the same behaviour with a trivial app which allocates a lot of structures and releases them after. -- You are receiving this mail because: You are on the CC list for the bug.
