Home Assistant - High Memory Usage


I have been noticing high memory usage for about a day or so. Tried to disable automations, add-ons, to remove almost everything from my configuration but the memory calculation as per the system monitor sensor is still high ~ 75%.

I am running Home Assistant 0.107.5 (latest) in Docker on Open Media Vault distribution and RPI4 4GB memory hardware. The strange thing is that when I ssh in OMV and check the memory, used by the containers, homeassistant uses about 80MB which seems ok. I am attaching some photos with the output of the top command and from the HomeAssistant UI:

This is from the OMV Terminal - top command:

This is from the OMV Terminal - free command:

This is from the OMV Terminal - docker container stats command:

I really don’t see what’s eating up the memory (if the 75% calculation of the System Monitor is correct as I am starting to doubt it…). Would appreciate if you guys can give me tips on what I can check in order to spot the culprit.



For my PI3b+ … HA is unsuable after a couple of hours… Got less than 80Mb of free memory… before I had 300… It’s so unstable that I had to turn off the 3B+… and I will kill soon my microSD. There is a huge memory leak problem IMHO with last releases

I have also faced this, luckily I run mine from a VMware esxi server it had 8gb memory and maxes out Nearly all the time. This has only been since the upgrade. It’s not a major issue for me as I just changed the memory to 16gb to solve the issue but it used to be minimal memory now it’s crazy since the upgrade.

Yep, As of 106 I believe the memory has been crazy.

I used to sit at less then 1gig used, now its always 3+ and if i leave it open all day, it will get to 100% used and swaping almost 1g as well. So its leaking on the client side as well.

Only thing open, 1 instance of chrome with ha loaded in it.

Definately something going on.


For clairifcations purpose: the first picture is from one of my desktops, all that its used for is editing and ha related stuff.
Second and third is my Ha server.

Typical Free memory graph on my PI3B+

On last 30 days


and last 2 days

We can clearly see the memory leak in action

Same issue here.
I see peaks in the memory usage every 6 hours, sometimes eating all the available memory and blocking the Pi3b.
I have no automations that run every 6 hours so I don’t know how to find this thing.
I hope someone can tell me how I can solve this.
