<br><font size=2 face="sans-serif">Thanks to some help from Henrik I have
solved my purple messages and hobbitd_client crashing problem. The clue
was in the gdb analysis which I had noticed but wasn't totally sure what
it meant.</font>

<br>
<br><font size=2 face="sans-serif">The problem is to do with regular expressions.
Henrik suggested my bb-hosts but I have no regex's configured in there
so I went to check my hobbit-alerts.cfg and hobbit-clients.cfg. As I'm
not too good with regular expressions I started by commenting out all the
most recently added custom alerts and narrowed my problem down to a few
custom alerts where I had tried to tell hobbit which messages to ignore.
I need to add some better rules to allow me to better detect the messages
I want and ignore a few messages which I don't want.</font>
<br>
<br><font size=2 face="sans-serif">In the process I asked Henrik if he
had any regex checking tools, but went out and did some searching myself
as well. I found quite a good tutorial at http://www.regular-expressions.info
(with a lot of encouragement to buy their regex capable text editor and
some other regex tools), as well as a number of freeware regex checking
tools that might be useful to others both in learning and testing regex
configurations.</font>

I posted a new query a week or so ago because I was having the same problem
even after I had added --no-ares to my hobbitlaunch.cfg so I thought it
might be a different issue.</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
Yesterday I tried moving my hobbit workload to a Fedora 6 system and I
have the same problem. This is no longer erratic, it's all the time. Any
other suggestions?</font><font size=3> <br>

See http://www.hswn.dk/hobbit/help/known-issues.html#bugreport for<br>
instructions.<br>
<br>
Adding a "--no-ares" option to the bbtest-net command in<br>
hobbitlaunch.cfg might help; we know there is a bug in the C-ARES<br>
library used for DNS lookups, but it is apparently something which only
<br>
triggers occasionally (or in specific setups).<br>
