I am running supervised on Debian 11
My install has been unstable for months and I have been fighting it.
First thing I found was my disk was filling up this was causing things to not load on boot and to crash.
It took me some time to track down the culprit (it was not log files)
It was the adguard integration database. I found it by running this command to show me files ove 1Gb
sudo find / -xdev -type f -size +1G
That showed me large files, from there I tracked it down removed the integration deleted the file and all was well. (the file would grow very fast to fill all available space)
Now everything loads but is still running slow intermittently.
Top showed me that my mosquito broker was using 40% of my available memory.
I shut it down and everything was fast again, but I need it so this was not a solution.
I then increased my swap size from 1G to 2.5G, this helped a bit but not much.
After much googling I came across a post that was only peripherally related but I figured I would try the advice.
Ran the command
sudo sysctl -w vm.drop_caches=1
using the command
free
I could see my a little of my cache freed up.
hass:~$ free
total used free shared buff/cache available
Mem: 3861228 3273788 208596 472 378844 393432
Swap: 2536440 1683748 852692
hass:~$ free
total used free shared buff/cache available
Mem: 3861228 3266804 249892 472 344532 398500
Swap: 2536440 1683748 852692
The buff/cache would generally get over 500000
these screenshots are after my “fix” which runs through a root cron job every minute.
I am sure this is a very hacky way to mitigate the problem and I would love to get to the bottom of it. I am a good copy and paster 
but not a programmer so I put this up for any other poor bastard like me with this sort of issue. Any suggestions on how I might properly fix this are welcome. I am considering rebuilding my whole system when I am off around Christmas just trying to decide whether to upgrade hardware.
