Description:
I've seen MySQL servers crash with no specific error log message that turned out to be SIGXFSZ.  Would it be appropriate to add a signal handler for that to at least exit with an appropriate error?

How to repeat:
In my case I could reproduce this when MySQL was using a file > 2TB on an ext3 filesystem.  I suspect there are some easier ways to reproduce it.

Suggested fix:
Add a SIGXFSZ handler to at least emit an error message to the log before aborting MySQL

Hello Jay,

Thank you for the report and reasonable feature request.

Thanks,
Umesh
