Docker causing high reads and high load average
Been struggling with this one for a while
I have quite a few Dockers running but nothing extremely intensive for long periods. Current running list is:
Gitea
nginx
sabnzbd
unifi-controller
zigbee2mqtt
jellyfin
sonarr
PlexMediaServer
qbittorrent
homeassistant
pihole
resilio-sync
CrashPlanPRO
gotify
NodeRed-OfficialDocker
docker-bubbleupnpserver
After some period of time, sometimes it can occur in minutes sometimes it runs fine for weeks, the
It just happened again. Top says 2000MB cached. Top in the above screen shot shows 1800MB cached. So I don't think RAM is running out.
I also remembered I can simulate the symptoms with a big torrent doing a force recheck in qbitorrent on a huge file (46GB). That doesn't of course help much other than show that high read IO on my cache drive (qbitorrent download loaction), brings docker down.
