flexfax: Faxes dying after a certain amount of time

[Nick Riemondi <nick@outerscape.net>]

I am using HylaFAX to send out database queries to customers.  I have a
process create the faxes by running sendfax (there are about 200 of
them).  I watched the process closely and everything ran great.  About 3
hours after the faxes started sending the 150 or so still in the queue
died one after another in under a minute and sent an email to root
stating that the fax could not complete before the apointed deadline.
How do i set this?!  I have found in the documentation that it defaults
to 1 day, but mine died after 3 hours, still I can't figure out how to
set it.  Please Help!
Thank you so very much!
