terminate called after throwing an instance of 'json_spirit::Error_position'
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):

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
Then when gdb is started add these 2 commands:
set env LC_ALL=C
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.
--Type <RET> for more, q to quit, c to continue without paging--
