Default funny problem with process names

this is what i get when i type...
ps -Al
1 S 0 3 1 0 75 -5 - 0 worker ? 00:00:00 events/0
4 S 0 779 1 0 76 -4 - 372 - ? 00:00:00 udevd
5 S 0 2396 1 0 80 0 - 379 - ? 00:00:00 inetd
5 S 0 2406 1 0 80 0 - 1330 - ? 00:00:29 3
1 S 0 2449 1 0 80 0 - 480 - ? 00:00:01 3
1 S 0 2452 1 0 80 0 - 639 - ? 00:00:00 3
(trimmed)
seenow, those "3" processes are actually stuff like named, ulogd, dhcpd...
revealed by "ps aux" for example (which shows full paths not process name)
the thing is, ps -Al and killall search process names in /proc/$PID/stat
between (). and its wrongly there.
tried with last couple of 2.6 kernels, and not too sure its kernel fault.
so any ideas why /proc/$PID/stat gives process name as "3" and not
"dhcpd" for example?

problem solved. and i'm a retard.
i had a briliant idea to reduce boot time, by upx-ing bigger binaries that
start on boot (wifi router machine with old and slow hard drive).
those binaries were the ones displaying wrong process names.
/usr/sbin/named for example. which lead to problems, such
being unable to stop/restart service using /etc/rc.d/rc.service
stop/restart.
now, i also repacked those binaries using new 1.94 beta of upx. it
works flawlessly.
