Hobbit core dump every 5 minutes

[Brian Daly <brian.daly (at) criticalpath.net>]

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 - 


[hobbit (at) monitor server]$ gdb bin/hobbitd core.4115

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.

Any help would be greatly appreciated.
