I've recently found another another scenario in which the scheduler may die.
Syslogd was for some weirdo reason writing to /dev/console which because
it is a serial interface was blocking over a long time, therefore
all processes which were trying to log something to syslogd via /dev/log
were also blocking after that socket had filled up. The machine stayed
in this state for several hours until I was able to get to the serial
console which made the system recover. This scenario happend several times;
each time when the machine was in this state for a longer time which
probably means a some minutes or so the scheduler died.
This was zmailer 2.99.51 running on Redhat 6.1. Sorry, no core files
available and syslogd's records are obviously not helpful in this
