Hi Guys,
today my hobbit server started throwing up purple alerts for all my network (conn) and various other tcp connection tests. I noticed that a core file was being created every 5 minutes. Here is what gdb has to say -

This is the latest output from the bb-network.log file -
xstrdup: Cannot dup NULL string
not sure how to find out what version of Hobbit I'm running.
To show the version:
$ bbcmd bbtest-net --version 2011-01-19 09:03:48 Using default environment file /usr/lib/hobbit/server/etc/hobbitserver.cfg bbtest-net version 4.2.3 SSL library : OpenSSL 0.9.8e-rhel5 01 Jul 2008 LDAP library: OpenLDAP 20343
Try running the gdb again against the bbtest-net binary at /usr/local/hobbit/server/bin/bbtest-net on your system.
David.
