after a reboot, you could just try "postfix stop" and delete the lock
file, then "postfix start"
to find zombie processes, you could try "pstree" (shows a tree of
processes & sub-processes, in the order they were started at init time -
note that none of them are named postfix - the top-level process is
named "master") - you might have to install the tools, I think they're
part of the "process tools" package on Debian (but that's completely
from memory) - google is yourf friend

you have a zombie master process hanging around. Stop postfix. Get a list of
all running processes and check if there's a orphaned master process hanging
around. Kill it. Start postfix.
