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.

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.My buster box says pretty much the same thing. I’m not using zswap.Filename Type Size Used Priority /dev/dm-1 partition 10485756 0 -2I don’t recall ever having seen it actually use any swap, but that may just be me not remembering something that didn’t seem important at the time. Rick PS: I did manage, just now, to force it to swap a small, but non-zero, amount by opening lots of tabs in firefox. So it will use a “-2” swap partition if it has to. For what it’s worth, I noticed that firefox got kinda slow, but it didn’t freeze.
I run stretch on a t60p with 2GB of RAM, so i know it swaps as normal. But both I and the OP use zswap which probably sets the prority to -2, FWIW swap space shows 300MB with the zswap space compressed to 110MB
