[hylafax-users] Received faxes resent unnecessarily

[bill.allison@xxxxxxxxx]

Hello

I have a problem with faxes being resent to my hylafax server by the   
sending fax machine or it's operator in response to an error condition   
detected by the sending machine, even though the fax appears to have been   
received here without error i.e. both it and the re-sent fax are placed   
in the recvq and look identical when viewd or printed, and the session   
logs for both have, as far as my inexperienced eye can detect, no   
significant differences. This is happening with 5 to 10% of received   
faxes apparently at random.

I've searched here and on Google and not found a report of a similar   
problem. I've also searched man pages for settings that I might have got   
wrong, with no success.

Please tell me where / how to begin looking for the cause, which I do   
expect will be misconfiguration on my part. Below are my config files. I   
note the list's request to not include lengthy traces. Please let me know   
if you need example session logs and how / where to post them.

Version information:

modem USR 5630B (64-245-630-04)
OS SLE 8.1 (2.4.19-64GB-SMP)
hylafax 4.2.1 compiled from source

I received a fax today which although truncated, and the log was full of   
errors nevertheless it was placed in the recvq. Could this be connected   
to the above problem?

TIA
Bill A.
