Semantic model lost after restart

Thank you Rich, I set logging level to maximum in conf. and run openhabian-config. in log I found this

  • local ‘introText=You are about to activate the zram feature.\nBe aware you do this at your own risk of data loss.\nPlease check out the “zram status” thread at ZRAM status before p roceeding.’
  • local ‘lowMemText=Your system has less than 1 GB of RAM. It is definitely NOT recommended to run zram (AND o penHAB) on your box. If you proceed now you will do so at your own risk!’
  • local zramInstallLocation=/opt/zram
  • [[ install == \i\n\s\t\a\l\l ]]
  • [[ -f /etc/ztab ]]
  • [[ install == \u\n\i\n\s\t\a\l\l ]]
    ++ timestamp
    ++ date +%F_%T_%Z
  • echo ‘2021-05-29_07:23:38_CEST [openHABian] Refusing to install zram as it is already installed, please unin stall and then try again… EXITING’
    2021-05-29_07:23:38_CEST [openHABian] Refusing to install zram as it is already installed, please uninstall an d then try again… EXITING
  • return 1
  • ‘[’ 1 -ne 0 ‘]’
  • whiptail --msgbox ‘There was an error or interruption during the execution of:\n “30 | System Settings”\n\n Please try again. If the error persists, please read /opt/openhabian/docs/openhabian-DEBUG.md or https://githu b.com/openhab/openhabian/blob/main/docs/openhabian-DEBUG.md how to proceed.’ 14 80

As I understand, log said me, that ZRAM is installed. But now I dont know, what to try to get know why zram does not works correctly..
