Delete the call to logInfo, or don't run with such aggressive system 
logging.  These messages are generated with a priority that is two levels
below anything you should worry about and only one level above debugging

This doesn't seem to originate from Hylafax itself, unless it is new in
the betas.

This is almost certainly due to an OS bug.  Linux dynamically allocates port
numbers from a range reserved for server use.  Raise this one with Red Hat,
pointing them at a copy of the assigned numbers RFC.

If the system relies on ATH, it is misconfigured.  Modems should be hung
up by dropping DTR, not by the use of ATH, except as a fallback.  In any
case, you should obtain session logs for this one.  You should also consider
your telephone network suspect.

Condensed pages either result from receivers who don't realise that 
normal resolution faxes have an assymetric resolution, and have a poor
quality TIFF viewer, or from a sending system that has misconfigured
flow control.  Misconfigured flow control will also cause other

As it says.  Hylafax received an invalid response from the remote end/modem.

See log for details, but probably no response at all from the modems.

Line quality is too poor.  (Or one side or the other is requesting a
minimum speed which is faster than the maximum for the modem pair.)

Remote modem disconnected prematurely.

Answered by voice, or confused by automatic fax switch, etc.

No response to EOP is the only one where I think one could even suspect
Hylafax, although its problem might be acting strictly correctly for 
protocol violations, rather than pragmatically.

Provide the session logs.  This description seems to contradict itself.

Generally, to get help, you need to attack one problem at a time and document
it with a system log, configured for a high level of detail, together with
anything non-standard in your configuration.
