Fatal signal caught!

[Dan Vande More]

Here's an update.

If I only have one server in the bb-hosts bbtest-net doesn't fail with
any of these services:

<ip>     hostname # ntp dns conn ldap ssh2 ssh1 bbnet pop rsync bbd
ftps telnets smtps pop3s imaps nntps clamd ldaps vnc

If I use *any* of the other services, that is:

ftp
ssh
telnet
smtp
imap
imap2
imap3
imap4

I get an immediate:

2005-09-16 14:33:12 Adding tcp test IP=<ip>, port=143, service=imap, silent=0
Aborted (core dumped)

This might help too:

Whoa! Why's it looking for 0x4? Is that a bug?

Thanks
