I got stuck in the same situation:

# kill -9 91651
# ps -o pid,jid -awux | grep 91651
91651  11 root              0.0  0.0   101488   29344  -  TsJ Fri05       2=
:10.18 /usr/local/sbin/syslog-ng -p /var/run/syslog.pid

and I wonder if there is anything I can do to get rid of this process.
I had this situation last year too and ended up in restarting the whole
system. But now I can't reboot.

Thanks
Ole
