I'm pretty sure I ran into this same issue a while ago. I tried to use
/etc/apm/{powerup,powerdown} to switch between 'apm -C' and 'apm -A'
when undocking/docking my laptop. apmd didn't like being poked by apm
from those files. Just use apm in one of the related /etc/apm files to
reproduce.
[danh@t obj] $ cat /etc/apm/resume
apm -A
[danh@t obj] $ sudo gdb apmd
(gdb) set args '-d'
(gdb) run
Starting program: /usr/obj/usr.sbin/apmd/apmd '-d'

[... enter suspend, then resume here ...]
