Subject Re: [users@httpd] How to interpret server-status from mod_status module?
Date Thu, 02 Aug 2007 02:00:34 GMT
Thanks for the quick turn around.
The reason i had the doubt was since there are 7 other webservers in the
webserver farm to which the load balancer sends requests and only the first
one seems to have 400 slots shown. The others have of the order of < 200
slots shown - though the number of active workers on each webserver is
almost the same.

Thanks

Ramdas

Nah. You have 400 slots because MaxClients is set to 400 so apache
creates a scoreboard (inter-process communication location) with space
for 400 children to be tracked.

No, not unless you have a memory leak someplace.
