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     

bootparams: nisplus [NOTFOUND=return] files

ethers:     files
