You can only call this after you have loaded modperl and such. 
So it might be related to that.

This is because you can only use Apache::DB to debug perl code. 
mod_status.c (i.e. server-status) is written in C, so you will need to
use a C debugger such as gdb or dbx. See the earlier thread on that for
some useful hints.
  
Hope that helps,

RE: Debug perl package in Apache

[Wang, Pin-Chieh]

Hi Sander,
Thanks for the info, I read the article you suggested, and try to testout
the server-status (as oppose to the perl-status
as the example suggested,) but my testing was not quite right, hope you can
answer my questions

First I can't put the  block at the beginning of the
http.conf (I got httpd.conf syntax error 
when I run httpd -X -DPERLDB; Then I move the block to the end of the
http.conf file re-run the command then I get
% ./bin/httpd -X -DPERLDB
[notice] Apache::DB initialized in child 23415

the system is waiting for my call the request.
But when I call http://localhost/server-status I still don't got the debug
prompt. here I called server-status instead of perl-status. I guess I don't
understand how Debuger is configured into perl-status when
http://localhost/perl-status is called.
can you share some light on this?

Thanks,
PC
 The following is the additions in httpd.conf as described in the article.




   
  use Apache::DB ();
  Apache::DB->init;
   

   
  PerlFixupHandler Apache::DB
   



In our first example, we will debug the standard Apache::Status module,
which is configured like so: 
PerlModule Apache::Status

PerlHandler Apache::Status
SetHandler perl-script


When the server is started with the debugging flag, a notice will be printed
to the console:
