Repetier Server crashing - can you help?

in Repetier-Server
Some time last night, for the millionth time, a glitch caused all of my printers to freeze. Hoping for some insight. Here are my logs from server.log from around the time something could have happened until now:

    If you send a log you also need to tell us what you did when and when the freeze happened and what freezes. From log I see that printers loos connection. But did you disable them or did linux shut down usb port due to undervoltage and that was a result of it (assuming you are using a raspberry).
    Does the interface to server freeze or just print stop. If print stops, does connection get green again and you can send new commands? 

    Please check /var/lib/syslog around the freeze time for usb related messages.
    dmesg
    will show you if undervoltage happens from time to time. Not all messages cause a disconnect, but is a hint that it could be an issue here. If I see it correctly you are running 5 printers from one server so power, signals, usb bandwidth all could play a role.

    Thanks. No corresponding logs indicating a USB or under voltage problem. Also using high-quality power supplies, and not over taxing the Pi's resources.

    I unfortunately can't tell you what happened, as I was not watching the server as it happened. It was on a long print, 3 of 5 machines running. All stopped in place and reset during print. Connection re-established and I could send commands after the fault.

    could be interpreted like a server crash - at least it was not shut down cleanly and would explain all printers stopping. It is just impossible to say why. If this is a frequent issue you might need to debug it so I can say more.

    https://www.repetier-server.com/knowledgebase/debugging-crashes-hangs-on-linux/

    describes how to debug it. You need a constant putty connection with it running in gdb to catch it. The full back trace when it crashes is what I would need to find it.

    What version are you using? We fix constantly parts with each release as we find some points not working. Maybe tomorrow we release the next update to 0.92.2, so please upgrade as soon as it is out so debug report matches our sources.
