Hello,

I'm running 27 Prusa i3 MK3S+ printers off of a Linux installation of Repetier Server. I haven't had any issues until the past few days when the server randomly crashed multiple times. The first crash happend on September 5 around 14:00 and the server log shows the following:

Can you tell what happened to cause the server to crash?

Thank you!

    It look slike a crash, but there is no chance to say why without proper information. If there is a way to force the crash that would be something I can try on my computer and debug then. But such rare cases can only be debugged when you have it in debugger running and provide backtrace information on at leat the thread that did cause it in first place. See
    https://www.repetier-server.com/knowledgebase/debugging-crashes-hangs-on-linux/
    on how to do it. Before try reinstalling it just to make sure it has correct binary files and it is not from a corruption.

    Also did you change anything lately - might be a hint on what is causing this especially since it worked so well before?

    I have a core dump from the most recent crash; can I email that to you to look at?
  • RepetierRepetier
    That should work as well. I send you a pm regarding email.
