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.

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?

From my hobbitlaunch.cfg:

See http://www.hswn.dk/hobbit/help/known-issues.html#bugreport for instructions.

Adding a "--no-ares" option to the bbtest-net command in hobbitlaunch.cfg might help; we know there is a bug in the C-ARES library used for DNS lookups, but it is apparently something which only triggers occasionally (or in specific setups).

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. Reading symbols from /lib/libpcre.so.0...(no debugging symbols found)...done. Loaded symbols for /lib/libpcre.so.0

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.

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.

Not listed in any particular order (I'm still checking them out

to see which is most useful) - your milage may vary, and I don't endorse any of these apps or have any connection to any of them in any way: Regex Builder - http://renschler.net/RegexBuilder/ Regex Coach - http://www.weitz.de/regex-coach/ Regular Expression Laboratory - http://silveragesoftware.com/rxl.html Funduc Search and Replace Regular Expression Wizard - http://www.funduc.com/search_replace_wizard_ex.htm

Some are simple zip files, some require a Windows installation,

but you can use another tool called Universal Extractor to unpack them if you want to just test them without the formal Windows installation process.
