hi. i solved this problem(and some of others :) ) by fixing gem code.
i've submit (see prev. message in this group) a patch but it seems
that gem maintainer not watching this group very often.
so, i can help with source code only:
you can add someth like "log.sync = true" after "log = File.new("#
{daemon.classname}.log", "a")" in trunk/lib/simple-daemon.rb
