As a fore-note, I'm not subscribed to this list, so please CC me :) 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. root@tomoyo> uname -a FreeBSD tomoyo 7.1-RELEASE-p5 FreeBSD 7.1-RELEASE-p5 #0: Mon Apr 27 16:58:17 UTC 2009 bsdadmin@tomoyo:/usr/src/sys/amd64/compile/TOMOYO amd64 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!)
