I was just tweaking a php.ini file and restarted Lighttpd (via rc.d).
The rc script was taking forever to stop it (was waiting for the
process to terminate). After a couple minutes, I got impatient and
killed the rc script with ^C and issued a `killall -9 lighttpd`.
Much to my surprise, this didn't have any effect (and neither did kill
-9 with the PID). top showed lighttpd with the unchanging
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
85542 www 1 51 0 102M 85360K CPU6 6 16:34 100.00% lighttpd
Basically, wedged on CPU6.

Using SMP and SCHED_ULE.
I "resolved" the issue by rebooting the machine.
I guess my questions are twofold:
1) Should this be possible? What is going on here?
2) If this happens again, how should it be resolved? What diagnostics
can I run to further diagnose the problem?
Thanks a bunch for any help (and don't forget to CC me!)
