[hobbit] hobbit_client crashing on Solaris 9 hobbit version 4.2.0

Check your regular expressions. Henrik helped point me at that.

The fact that you're getting core dumps indicating libpcre points at a 
faulty regular expression somewhere.
You may have recently added something to one of bb-hosts, 
hobbit-alerts.cfg or hobbit-clients.cfg. If you don't know for sure what 
changed recently and can't easily see which regexp is bad, take one file 
at a time (start with hobbit-clients.cfg or hobbit-alerts.cfg) and 
suppress all lines with any regular expressions. Once you find which file 
has a bad regular expression, uncomment all that are clearly good, then 
uncomment one by one until you find which is not working right.

You might also find one or more of the regular expression validation 
programs I listed previously to be useful, though they are not guaranteed 
to be fully libpcre compatible.

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

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.

[hobbit] hobbit_client crashing on Solaris 9 hobbit version 4.2.0

The hobbit_client on my Solaris 9 server (which also runs my hobbit
server, version 4.2.0) went red last night (after several months of
perfect operation). 

Apparently hobbit_client keeps crashing and dumping core files, then the
hobbit server / channels process restarts it.  I tried restarting
hobbit, but the problem persists.

On the hobbit_client web page:
- Program crashed

Fatal signal caught!

in /var/log/hobbit/clientdata.log:
2007-04-04 13:43:23 Worker process died with exit code 134, terminating
2007-04-04 13:48:24 Worker process died with exit code 134, terminating
2007-04-04 13:53:24 Worker process died with exit code 134, terminating
2007-04-04 13:58:25 Worker process died with exit code 134, terminating
2007-04-04 14:08:27 Worker process died with exit code 134, terminating

and in /var/log/hobbit/hobbitlaunch.log:
2007-04-04 13:43:23 Task clientdata terminated, status 1
2007-04-04 13:48:24 Task clientdata terminated, status 1

2007-04-04 13:58:25 Task clientdata terminated, status 1
2007-04-04 14:08:27 Task clientdata terminated, status 1

I saw another post about these errors, and went ahead and ran gdb
against one of the core files:

Any suggestions?

Thanks in advance for your help.
