  Subject: mod_perl startup sequence?
  
  I'm confused about when mod_perl loads Perl Modules. It 
  appears my perl module gets loaded twice: once when the log writes to stdout, 
  and once when the log message is written to error-log.
  I would expect my module to only get loaded once. Why 
  twice? 
  To help me trace loading, I added "print STDERR" statements to 
  my .conf file and my perl module. To my surprise, log messages go to the 
  console, and messages go the log file 30 milliseconds later. Also, the 
  Apache::Server::Starting is 1 first time through, and 0 the second time 
  through. NOTE: PerlFreshRestart is NOT defined.
  For example, this appears on my console: # .conf started at 983839924.241642, Starting = 1, ReStarting=0 
  # wierd.pm started at 983839924.274978, Starting = 1, 
  ReStarting=0 # .conf finished at 
  983839924.277637 
  And this appears in my error-log: # 
  .conf started at 983839924.285614, Starting = 0, ReStarting=0 # wierd.pm started at 983839924.292273, Starting = 0, 
  ReStarting=0 # .conf finished at 
  983839924.294823 
  Notice the difference in execution times (1st ends at 
  983839924.277637 and the 2nd one starts at 983839924.285614). 


I have a similar confusion.My httpd.conf opens with

LoadModule 
perl_module modules/mod_perl.soPerl open FIL, 
"c:\\a.txt"; print FIL "\nStart httpd.conf 
pid=$$"; close FIL;/PerlAfter starting 
Apache I have the following in c:\a.txtStart httpd.conf 
pid=2144Start httpd.conf pid=2144Start httpd.conf 
pid=2072startup.pl is also run three times.The config is win2k, 
apache 1.3.17, mod_perl 1.25. The taskmanager shows two apache.exe's running and 
two cidaemons. I could understand a fallback apache, bit I cannot see why the 
code is executed twice for the same pid.Can someone explain this 
behaviour - or tell me where I should go to read about it.

And this appears in my error-log:

Here's my simplified .conf
Perl
 use Time::HiRes qw( time );
 print STDERR # .conf started at  . time() . \n;
/Perl 
PerlModule wierd.pm
Location /my_wierd
 SetHandler perl-script
 PerlHandler wierd
/Location
Perl
 use Time::HiRes qw( time );
 print STDERR # .conf finished at  . time() . \n;
/Perl 



And here's my simplified wierd.pm
package wierd;
use strict;
use Time::HiRes qw( time );


print STDERR # wierd.pm loaded at  . time() . \n;
return 1;
