Please double-check this by looking at the files in 
/var/spool/hylafax/sendq and checking that the "tts" entry is exactly 
the same for all of them.

This would either suggest that 1) the tts are not identical between the 
jobs, 2) that you may not actually have that scheduler fix, or 3) that 
the 1-second delay is not enough.

In all of the testing that I've been doing over the past several days 
(on a little PIII-500 w/128MB RAM) with this, one second has always been 
enough for 64 jobs (the maximum batch size) that are scheduled at a 
specific time.  I'll do some more testing with this, of course, but 
please double-check the tts settings in the sendq files and double-check 
your code.

You should probably update to current CVS HEAD.  There were some commits 
yesterday related to batching that you'll want.
