in Bug Reports
Server is running on RPi B+ with a 32 GB SD card. After sometime like an hour or so, the server disconnection message appears and the server tries to reconnect every 40 seconds. On running
export LC_ALL=C
sudo -u repetierserver /usr/local/Repetier-Server/bin/RepetierServer -c /usr/local/Repetier-Server/etc/RepetierServer.xml

The following log is generated (The server fails to start. The last line indicates an error after which the restart process is terminated. Any suggestions on this will help. Repetier-Server v35 for Bullseye is on the RPi):

    Ok that is hard to say from this info. json_spirit is the library used for dataexchange so always used when communication starts and that is exactly when it happens. To narrow it down you need to start it in debugger, but first login via ssh to the raspberry and update it to latest version with:
    installLatestServer

    If you have no gdb command install it with
    sudo apt install gdb

    Now start it in debugger if it still does not work. Enter
    export LC_ALL=C
    sudo gdb --args /usr/local/Repetier-Server/bin/RepetierServer -c /usr/local/Repetier-Server/etc/RepetierServer.xml

    Then when gdb is started add these 2 commands:

    set env LC_ALL=C
    r

    it will crash and now run

    bt

    sometimes this shows an endless list. We only need the start where lines differ. That way we can say in which function it is crashing to narrow the source.

    Me guess would be the printer configuration file /var/lib/Repetier-Server/configs/WL216A_Printer.xml but it can also be anything else. When you post the backtrace I check the code and can say more.
