kioexec core dump

[Vizion]

I have the following, and a number of similar entries, in my syslog:

Nov 20 09:04:20 dns1 kernel: pid 2285 (kioexec), uid 10: exited on signal 4 
(core dumped)

does anyone know where I should be looking to track this down? I tried a 
search for kioexec on freebsd.org docs without finding anything
