Probably this is related to a change in GhostScript.
GhostScript now has a slightly modified default format for tiffg4 output files. There are two options to fix this:
1. add option -dMaxStripSize=0 to the gs command to get the behavior of previous versions, or
2. post-process the TIFF file created by gs.

As an alternative workaround you can add
Use2D: no
to /etc/hylafax/config. With this HylaFAX will instruct gs to create tiffg3 format instead of tiffg4.

Based on other proposals I fixed the problem by inserting a post-processing with tiffcp in /var/spool/hylafax/bin/ps2fax and pdf2fax.
See attached patch.

See also Ubuntu bug report
https://bugs.launchpad.net/ubuntu/+source/hylafax/+bug/580568

This includes a different fix that adds
- -dMaxStripSize=0
to the gs command line, but only for ps2fax. A similar patch is needed in pdf2fax.
