Unfortunately, no one has reported this problem.
However, I found that the same problem occured on my FreeBSD machine.

I found a work around to avoid this problem.
The work around is change the time in line 51 from 1 to 10 or something.
I suppose that some kind of racing condition occurs between daemon
command in line 48 and cat command in line 52.
I also found that the same problem occurs even in dkfilter_in.
This might also avoided with the work around above.

I also made a patch, which is attached to this email.
With the patch, dkfilter_out script will spin wait until a size of
a temporary file becomes larger than 0, instead of just wating 1
secound.  This patch fixed the problem on my FreeBSD machine.
If the patch solves your problem, please let me know.
I will sendpr this.

Thank you,
Yoshisato YANAGISAWA.
