Thanks for the report. Without a stack trace, it's hard to know what to do with it.
Can you reproduce this? Do you know what data or request was active at the time?

It's a weird crash, I didn't find a way to reproduce and no interesting found in istatd-server log. Though it happens twice today. Is there a way to prepare a stack trace? So I can wait it happens next time and provide more info here.
