Well, subject says all. Mysql died on me repeatably :(

SMP system, dual 300Mc, not overclocked, Asus P2B, 128MB
Did not happen in the 2+ weeks I ran 2.2.14 previously, but
I was doing some hard database crunching with 100.000+ records
just now...

ksymoops 2.3.3 on i686 2.2.14. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.2.14/ (default)
     -m /boot/System.map-2.2.14 (specified)
