This is a weird problem... I have these problem during NetBSD 9.0 -> NetBSD 9.1 I also check this post and the final solution after all is switch to NetBSD-Stable branch. https://www.unitedbsd.com/d/171-netbsd-90-huge-memory-usage That is too bad. I don't want to move to NetBSD-Stable branch right now. And I don't want to throw NetBSD out of my world. I hope I can find solution in here. I have read https://en.wikipedia.org/wiki/Memory_paging#Unix_and_Unix-like_systems and I think I know a little bit. The only thing I want to do is enable swap space here is my `/etc/fstab` `/dev/wd0a / ffs rw 1 1 /dev/wd0b none swap sw,dp 0 0 tmpfs /tmp tmpfs rw,-m=1777,-s=ram%25 kernfs /kern kernfs rw ptyfs /dev/pts ptyfs rw procfs /proc procfs rw /dev/cd0a /cdrom cd9660 ro,noauto tmpfs /var/shm tmpfs rw,-m1777,-sram%25` here is my `mount`: `/dev/wd0a on / type ffs (local) tmpfs on /tmp type tmpfs (local) kernfs on /kern type kernfs (local) ptyfs on /dev/pts type ptyfs (local) procfs on /proc type procfs (local) tmpfs on /var/shm type tmpfs (local)` I sometimes see `swapctl: adding /dev/wd0b as swap device at pririority 0` when I boot to the system. And how to can I use `swapctl` or something to enable swap?

Need help...

strawman2511 I don't want to move to NetBSD-Stable branch right now.

Why?

strawman2511

I don't know that NetBSD-STABLE is difference than FreeBSD-STABLE. FreeBSD-STABLE mean still testing and still have some bugs before they have major release.

pin Why?
rvp (Or are you an entomologist?)

Heating my NetBSD box? I don't usually do that and I don't like wasting time.

I can still do it but do I have others choice?

I don't like pkgin so that is the reason why I took a lot of time in compilation. And now my NetBSD box hotter than FreeBSD and OpenBSD. So hot...

strawman2511 The only thing I want to do is enable swap space

Going by your fstab it should be enabled. Post the output of these 2 commands:

# Show swap statistics
swapctl -l > swapctl.out.txt

# Show top 20 memory hogs
top -n -ores 20 > top.out.txt

STABLE is where you should be, because STABLE = RELEASE + latest bug-fixes.
(Or are you an entomologist?)

strawman2511 like @rvp said, STABLE = RELEASE + latest bug-fixes

I'd add security-patches to that.

strawman2511 I don't like pkgin

To everyone its own.

EDIT: In case you don't know, upgrading from 9.1_RELEASE to 9.1_STABLE does not require a re-install. You can do it using sysinst or sysupgrade, pick your poison. I always use sysinst.
Moreover, the binaries you've already built will run on STABLE without itches.

Fun fact:
OpenBSD and NetBSD always force users to become advanced user even they don't WANT TO.

I am out of mind 😮

strawman2511 always force users to become advanced user

Nah! Here's how I do it, https://www.unitedbsd.com/d/110-upgrading-netbsd-using-sysinst

strawman2511

I am sorry, but what happen if I already destroyed NetBSD. Is there any netbsd-stable.iso file for me to make a USB bootable?

strawman2511 Yes, you can get daily STABLE images for 9.1 here, http://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-9/latest/images/

strawman2511

Okay, but I have moved to NetBSD9-Stable and don't see any difference between NetBSD9.1 and NetBSD-Stable. I still have the same issue, that is swap space doesn't work.

rvp

strawman2511 that is swap space doesn't work.

No swap space is being used because the system has sufficient memory. It's working perfectly.

BTW: there's no need to post screenshots. Just redirect the command's output to a file, then just paste it here. (See updated commands, above.)
