Nagios 2.0 problems starting [Resolved]

[Justin Lambert]

I first tried running gdb on the "make install" version of the nagios 
binary, gdb said there was no debugging symbols found, so I figure that 
wouldn't be as useful.  Copied the pre-make install binary (md5 sums 
different) and ran gdb on that.  Here is the output:

Program received signal SIGSEGV, Segmentation fault.

After seeing this I see lines about reading initial_state_information. 
I tried moving the saved state files somewhere else and nagios appears 
to be working now.  Thanks for your help guys
