This is a problem.  There can only be frames up to number 255.

The code responsible here is faxd/Class1Send.c++ at approximately line 
955.  The number mentioned there in the logs ("fnum" in the code)is 
defined as type u_short.  It does this:

   for (u_short fnum = 0; fnum < frameNumber; fnum++) {
       ... stuff ...
   }

Somehow it thinks that 255+1 = 2336

As you're using a platform (and probably a compiler) that is largely 
untested (OS X 10.3.8 is rather new), I'm guessing that the compiler 
doesn't like u_short.

According to the information I have, we're *supposed* to have 16 bits 
with a short type.  As 0-255 only consume 8 bits, I can only suppose 
that your compiler is only allocating 8 bytes to shorts.  If this is 
correct then this could be a problem throughout the code, as HylaFAX 
uses shorts quite frequently.

You could do a couple of tests, perhaps.  Change the code to read...

   for (u_short fnum = 0; fnum < frameNumber && fnum < 256; fnum++) {
       ... stuff ...
   }
