Deadlock problems with 'kill PID' on CURRENT

[Martin Blapp]

Hi all,

I'm experiencing on 6.X SMP still some deadlocks. The are not
easy to trigger, but each time it happens after killing some
PID's:

This time it was named. I just did this 5 times:

/etc/rc.d/named start (/etc/rc.d/named is broken and does not work)
ps -auxwww | grep "sbin/named" | grep bind | awk '{ print $2 }' ¦ xargs kill

and boom, it deadlocked and I was not able to get into DDB.

Any ideas where the problem could be located ? I've also seen the same
problems on 5.X.

Martin
