Since I posted a summary this morning, I received one more interesting
reply. So I am sending an updated summary.
I have recieved 2 responses.
Response 1 was from antonson@umiacs.UMD.EDU. He suggested that I dump
gnu netfax and go for Flexfax instead.
Response 2 was from P.G.Griffiths@dl.ac.uk. He seems to have a fix that
he is testing at the moment. If it works he will share it with me and I
am sure with anyone else who needs it. (Thats right Paul?)
Thank you.
Gautam

Um. Don't speak too soon. :^)

A package that causes regular reboots of systems does not work (IMHO).
Anyway, I played with GNU fax for about a week quite some time ago and I
trashed it in favor of FlexFAX written by Sam Leffler. FlexFAX is free
and you can get it from sgi.com:sgi/fax.
There is an email mailing list set up for flexfax users as well so there
is some external support if you run into problems. FlexFAX is written in
C++ and can be compiled with GNU CC/C++.
Hope this helps!

Hey, you live in a mirror world of ours, and you must be me, cause I have an hourly job that runs the faxq command and restarts the server on error... yup we see exactly the same problem as you.
Solutions: a) I split the spooler up into two parts, an incoming and an outgoing; did'nt really solve anything.
b) ran a trace to find out where the hang was --- took some time but narrowed it down to the select in read_internal(), I don't think it times out!!! Haven't yet attempted fixing it (only found out last week and not sure what effect fiddling with this bit of code will do) but I will attempt a fix here. Are you interested in the result?
Have you spoken with the authors?
Yours, Paul
