Are your ZRAM file systems running out of room? When it stops responding, ssh to the machine and run dh -h and see if any of the “overlay” file systems are out of space.

In this moment I have this:

but I had to restart zram.

I turn off zram and I have this:
openhabian@openhabian:~ $ sudo df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 29G 8.3G 20G 30% /
devtmpfs 454M 0 454M 0% /dev

Is ok ?

Two of your file systems are 100% full I’d start by looking there.
Also, what’s in the logs? openhab.log and the syslog?

I don’t know anything about zram but for comparison here is my output with Zram running;
openhabian@openhab:~ $ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 29G 8.5G 19G 31% /
devtmpfs 454M 0 454M 0% /dev
tmpfs 487M 0 487M 0% /dev/shm
tmpfs 487M 3.1M 484M 1% /run
tmpfs 5.0M 8.0K 5.0M 1% /run/lock
tmpfs 487M 0 487M 0% /sys/fs/cgroup
/dev/mmcblk0p1 253M 49M 204M 20% /boot
/dev/zram1 469M 57M 377M 14% /opt/zram/zram1
overlay1 469M 57M 377M 14% /var/log
tmpfs 98M 0 98M 0% /run/user/1000
What looks odd are your 2 files that are at 100% do not have an “Overlay” and then they do not go away when you stop zram. Maybe just delete them?
Do they disappear in case the system is booted ? Look like they are a left over.

At the moment, after turning off and on again Zram openhab does not want to start and I have it
