This has happened two times. The server randomly crashes and I'm not sure why.
I managed to get the last message displayed, and it's
<imput> <0>: Unable to find function handlePunchConnect
after spamming around 4 lines of punch packets.
Well, I kinda lied. The server doesn't crash, it just lags so much that everyone times out and nobody can connect, and anything I type in the console appears a minute later.
I haven't installed any add-ons, however on the 2nd crash I disabled JVS and enabled some other add-ons.
Both crashes did the same thing.
