I put three ktraces at
http://intrepid.warped.com/~scotte/visible/syslog_ktrace/ , and noted an
interesting behavior. The first time I execute syslogd after boot, it
produces the output shown in syslogd_Uses100PercentCPU.txt, while using
100% CPU (or close to it). If I kill syslogd (-9 is the only signal
that works), it will restart and work perfectly fine, as shown in
syslogd_1.txt and syslogd_2.txt.
I cannot get the system to hang, as I can when enabling syslogd on boot,
just use lots and lots of CPU. This is the behavior that I saw before
in the Oct 24-ish -current (although the syslogd 100% cpu trick happened
occasionally, and the initial run at boot didn't seem to cause the problem).
Let me know what else I can provide. Thanks!
