I am getting some octave crashes or sudden exits. 2 or 3 times per day.

Ubuntu 18.04, 5.0.0-23-generic kernel.

I am running octave in an xterm with:
/usr/bin/xterm -T Octave -en UTF-8 -j -sk -sb -sl 1000 -fn 9x15 -bc \
        -bg white -fg black -geometry 80x55 -e octave --no-gui &

Octave just exits.  I hesitate to call it a crash because there is
nothing in dmesg and nothing in syslog, etc.

I do not think any specific action consistently causes the exit.

Any ideas on how to possible track this?

Works for me (on Fedora).
Did you check journalctl?

Try running "bc" instead of octave.

Try running without "&"

Try to start octave inside  xterm manually.

Octave works fine, most of the time. Just a few, seemingly random exits. Nothing in journalctl. Starting octave with the xterm -e command has worked fine for a long time. Years!

I will try starting an xterm and then start octave manually. That should allow me to see any exit messages. I don't remember where they go when I use xterm -e. Getting old!
