However swap usage is still high : free -m total used free shared buff/cache available Mem: 15887 8577 1187 4587 6123 2382 Swap: 4095 3854 241
It's weird, isn't it?
It's consistent. Only ~240 MB of 900M for PK had been evicted to swap. When restarting PK, it dropped those 240MB in swap. Free memory also went up no doubt. I don't know why it's using so much memory, what all these anonymous pages are. If you catch it going above 500M, check /proc/pid/status and let's see what the breakdown is of memory usage.
Ok but smem tell me that around 300M is swap used, and the ~3.5G remaining??? Is there a way to find the culprit processes? Thanks in advance!
I'm not familiar enough with smem to know what it does or why it's missing things, but
for file in /proc/*/status ; do awk '/VmSwap|Name/{printf $2 " "$3}END{ print ""}' $file; done | sort -k 2 -n -r | less
Finds more things using swap than smem. As in, smem isn't showing packagekitd for me at all, and yet /proc/pid/status for pk is showing VmSwap is 16M, which at the moment is 20% of swap.
What do you get for zramctl?
Ok for some reason 'sudo' gets me different results with smem. Try this:
sudo smem -t --sort swap
