Description

This is a new (to me) style of crash: complete lockup.

Looks like the java process couldn't write to the console anymore? I'm a bit stumped here.

Offhand possible cause: Java process runs inside a screen session, and GNU screen will block console IO if it receives an XOFF command...but nobody was on a terminal session around the time of this crash, and nothing in our tools interact automatically with the screen session.

GNU's XON/XOFF behavior:
https://www.gnu.org/software/screen/manual/html_node/XON_002fXOFF.html

Nothing exciting in logs, although I'll hold onto them for 30 days, please request URL. I don't think this crash is network related, but tcpdump files have been set-aside as well. Also kept copies of VisualVM's snapshot (nps) files if desired, screenshots are attached.

Only deleted my IP from screenshots:

So for quick lookup or searching:
obfuscated.aDC.a()
was the function that took most CPU time, beside
Java.io.PrintStream.PrintLn()
