OK, I removed the 4.1.8 rpm and installed the source for 4.2.0. I
compiled the source and installed it successfully but had same signal 11
problem as I had previously when I was using the 4.2.0 rpm.
I downloaded and installed the 581 patch recompiled/installed but the
problem was still there.
I tried changing the nsswitch.conf file group line to compat but that
didn't make a difference.
I then recompiled with the --disable-pam switch and the problem went
away!!! So you were right. This has something to do with my pam
configuration.
I have attached the following files as requested...
/etc/nsswitch.conf
/etc/pam.d/hylafax doesn't exist
/etc/pam.d/other
I don't know how to get a trace of hfaxd during a connection. Let me know
how and I'll provide it if required.
This server is running Fedora Core 2. It has been upgraded many times
starting with a very old version of Redhat. It has undoubtedly got a lot
of garbage stuffed away in dusty corners and is well overdue for a clean
install...but it is generally very solid!

#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
# nisplus or nis+ Use NIS+ (NIS version 3)
# nis or yp Use NIS (NIS version 2), also called YP
# dns Use DNS (Domain Name Service)
# files Use the local files
# db Use the local database (.db) files
# compat Use NIS on compat mode
# hesiod Use Hesiod for user lookups
# [NOTFOUND=return] Stop searching if not found so far
#
# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd: db files nisplus nis
#shadow: db files nisplus nis
#group: db files nisplus nis
passwd: files nisplus
shadow: files nisplus
group: files nisplus
#hosts: db files nisplus nis dns
hosts: files dns nis
# Example - obey only what nisplus tells us...
#services: nisplus [NOTFOUND=return] files
#networks: nisplus [NOTFOUND=return] files
#protocols: nisplus [NOTFOUND=return] files
#rpc: nisplus [NOTFOUND=return] files
#ethers: nisplus [NOTFOUND=return] files
#netmasks: nisplus [NOTFOUND=return] files
