Re: [users@httpd] How Apache manages all its children - Add More Info

[jayaram.g@xxxxxxx]

Hi,
In windows Apache creates 2 processes.
Prefork is not supported on wondows. 

Process 1 has minimum  of three
threads as below.

worker_main ( actall thread which does
the work coded in modules. More threads are spawned accoding to the configuration
on httpd.conf )
winnt_accept
and __tmainCRTStartup

Process 2 also has three threads.
service_nt_main_fn 
service_nt_despatch_thread
and __tnaibStartup.


I wonder if anybody has tried Windows
prefork for Apache 2.2.2.  Prefork model adds to the stability I feel.
I am not sure if code in one thread corrupts the heap what will happen?
Will the Apache stopping further requests which actually goes through the
happy path of the code?  Do we need to restart the Apache??

Regards,

Jayaram Ganapathy

You can see some information on the child processes by
enabling the /info URL in httpd.conf - but you probably knew that already.

of them are in the service to clients, which of them
are Idle, etc.? Can some one give me a brief
description or refer me a URL/books?

Many Thanks, Q.Xie
