Describe your issue:

After some unsuccessful changes, ARMBIAN crashed. I decided to install a new image using the Armbian imager. Armbian version 26.8.3, trixie, tty 1. I created the klipper account, gave it sudo privileges, dilout ttl , and made some changes to visudo. After that, I installed git, the zlib1g-dev and libjpeg-dev libraries, and then proceeded to install kiauh . Klipper then installed without errors. However, Moonraker would occasionally freeze or return an error like

Hi @V2m

How did you tell you were only using 15% of the space on the SD card? Could you please share the output of df -h?
