"premature end of script headers" and schedules being skipped in 2.0rc2, CVS. Not present in 2.0b6

[Eli Stair]

Last week I started testing rc2, and began having problems when 
interfacing with the CGI's.  I get these at seemingly random intervals 
when accessing hosts, both viewing status and forcing checks/downtime, 
etc.

I'm also seeing an issue where service checks aren't being scheduled and 
executed, no indication as to why they aren't added to the queue and run 
on time.

Steps I've taken to track this down:

Verified same exact config is in use from 2.0b6 (where it worked fine).
Rebuild without embedded perl.
Rebuild without event broker.
Build on 2.0-CVS (2005-1-23)

The same issues are recurring.  Moving back to 2.0b6 fixes the problem. 
  What info can I provide to help track this down and resolve it?  Which 
debug output modes are useful to you?  Let me know any info I can provide.

Regards,
