Before posting here, make sure you are on the latest Beta or Stable version.
If you have problems related to the web gui, clear your browser cache + appcache first.
You cannot revert back to an older version, at least I would not advise it. If so you have to go back to an old database too.
You are showing memory usage of the machine. Is memory usage of the Domoticz process showing the same issue (see motherboard sensor device Process Usage)? If not it is another process on your machine that requires memory.
It seems you are not using Python plugins so it should be in the scripts somewhere.

I did not use a previous beta. Previously I used the release versions. It started last with the update in december. But in the meantime I also created additional scripts such as a (gas) degreesdays script.
Good point about the system mem. However I am certain it is the domoticz process, since restarting solves the issue. For example. This is the current system mem

Is there a way to quickly determine the memory usage of the Domoticz subprocesses?
Perhaps someone knows a better way to debug this but I would start with disabling the degreeday script for a day and see if the memory leak stays.
Do you restart only the Domoticz process or the complete system? You have a device called "process usage", please check that to be sure it is Domoticz (probably is)

You could try to look for the culprit with programs like gdb and pmap, but that is a tedious process.
I had the same kind of issue at the end of december / start of januari.
I my case I found out that it had probably to do with a system update in mid of december, I did not investigate which program was the 'bad guy'
But it might have to do with 'python3-urllib3'
I have a btrfs system and make snaphots every hour/day, so I just put the system back to before that update, and my problem was solved.

I did some testing last weeks. The leak correlates with enabled hardware, not with any script. More enabled hardware = more memory leaking away.

Yesterday evening I disabled most of the hardware. At 3:30 the daily restart occurs. At 9:00 I disabled all hardware, except the PI-sensors. 11:30 I started to enabled hardware again.
Since I have in total about 800 devices I need to restart demoticz daily as after a day of two the OOM-killers kills the Domoticz process.
Today I installed the latest beta. Same issue persists.
Is it really that my instance is the only one that has memory leaks? If I start with a brand new install the same issue occurs. Cannot believe that I'm the only one having this issue.
No you are not the only one. I also have a small memory increase every day until I get an unresponsive Domoticz after a few weeks.
Still have not figured out what the cause is, but keep looking.

I am experiencing the simular behaviour. Running 2024.3 on a RPI Zero (made the build myself). I am now thinking of letting monit restart domoticz when it passes 75Mb of memory ( if total memory > 75.0 MB for 5 cycles then restart ). System info:
There are other processes running on the system (otmonitor, nodered, mosquito MQTT, monit) but they all keep running. Only domoticz crashes and is restarted by monit every once in a while after the used memory of the domoticz process has increased to around 75 - 85 Mb. I did not have this behaviour with previous 2023.x installations.
