Re: flexfax: Large number of errors with Hylafax and ZyXEL Omni modem

[David Birnbaum <davidb@chelsea.net>]

Well....the machine is certainly busy at that point, but it's a pretty big
machine; it ought to be able to do the whole thing with 128MB of memory
and two SPARC processors.  Plus, it's sending six faxes simultaneously of
the same image, so it seems odd that it's getting imaged each time.  I
have a PS timeout of like five minutes, and the image takes < 0.5sec to
image (it's pretty simple).

Perhaps some more info would help.  Basically, I create one job and then
suspend it.  I then "clone" the job to send out 1200 copies of it to our
user community.  Of the 1200, maybe 0.5 fail (ie, every couple of days).
So...the question is, can I turn on more specific debugging that says
*why* HylaFax can't open the document file?  It's impossible to replicate,
and of course, by the time I look at things, the document file is there.
Not being a real C hacker, I don't know how much debugging I can
comfortable put into the code....

Suggestions....   ?

David.
