I do run openhab 3.4.3 on my raspberrypi 3.
If it runs for about 2-3 days, I get several timeouts, and openhab and the whole raspberrypi is not responsible till I kill all openhab sessions and reboot.
the first indicator in the openhab.log is an alexa binding, and after that all http binding make timeouts:

I have a rule to determine if my network is going down. (pings). but I don’t want to reboot in such case… I want to prevent such problems.
how can this be done?
Thanks
only in openhab.log the problem with alexa… this causes problems to WAN and LAN connections. I have a rule for ping my inverter, and get notified by telegram.
Tackle the root cause and get your network stable.
If you use a hostname in your rule to ping you can try replacing that by its IP but ultimately the problem is not in openHAB so to fix your problems, you’re looking in the wrong place.
I’d investigate DNS and DHCP setup. Ever-assigning the same IPs to devices on DHCP is a good start.
I found some topics with ALEX Echo Dot Binding if this getting offline to WIFI connection. It can occur because my echo dot has not the best wifi connection.
When the problem occurs, all my network components are accessable, instead from openhab. a simple ping from raspberrypi is also possible.
No info in syslog or dmesg only in openhab.log is represented.
Therefore I think this is a problem of openhab / a specifiic binding in openhab.
ok, i have some interesting infos! I had a power failure exactly at 3:25 p.m.
After that my DHCP Server has gone and the wifi Access Point for Alexa Binding also.
It took about 3minutes getting up the wifi AP and the DHCP server. After that, the problem occured and did not resolve itself.

it’s on a raspberrypi 4. is that a problem ?

Very likely one of your rules or components which is embeded in openHAB causes a memory leak. In such case you need to isolate cause.
Start from disabling everythin but essential stuff and see if memory consumption keeps growing. If not, add another element. Until you find one which causes infinite hunger.
Percentage will differ depending on hardware you use. OH 3.0.x installations I have are staying with 512 megs (26% of system memory, I do not have xtext rules there). I do have an installation which keeps going with constant consumption of 1300 megs (37% of available memory), however it does not exceed that limit.
If you have pi4 with 8 GB of ram then 50% is far too much. Even with 4 GB its a lot.
And various settings in Java and OS. Assuming you have swap it’s more likely that any of those is your limit, but you didn’t provide reasonably much information about how you installed your system.
This model comes with 1GB of memory. If your openHAB takes 53% it is around 500 megs, which looks fine to me. Still, if its gets killed with out of memory error it means that it exceeds a limit. Whether it is a JVM memory limit or per process limit set by system - we have to figure out.
