Hi,

I am a Debian testing user. Recently I am experiencing freezing on my
Debian system intermittently and during troubleshooting the same, I
found out that the I have a swap partition with priority set to
-2. But according to the below manpage:

https://manpages.debian.org/stretch/mount/swapon.8.en.html

swap priority should be between -1 and 32767. I have a swappiness
value of 60 but I don't remember seeing the swap being used at all
recently, the used swap is always 0%.
Whats swapon -s say? do you use zsawp or zram?
Filename                Type        Size    Used    Priority
/dev/sda5                                  partition    8203260 0    -2

I am using zswap.

My question is, do you think that the -2 priority is stopping the swap
partition from actually being used and because of that, the system is
getting frozen when the memory usage is high?
No, it's -2 on my stretch box with zswap enabled and it swaps as one
would expect.
