[hylafax-users] Faxes not received properly; no error messages

[Toralf Lund <toralf@kscanners.com>]

My hylafax installation - version 4.1.2 on SGI IRIX - has suddenly stopped 
receiving faxes properly. It will answer incoming calls as expected, and 
also create the output file, but before actual data is written, the 
sending fax will exit with "communication error" and hang up - or maybe 
hylafax disconnects first, it's a bit hard to tell. In any case, I'm left 
with a 8-byte TIFF file and a log file that doesn't really tell me 
anything; an example is attached. This appears to happen for faxes from 
several different senders. The setup has been running without any major 
problems since I last upgraded the software, which I did about a year ago, 
and I haven't touched the config since then (not consciously, anyway...)

Ideas, anyone?
