Hi,

I have below error :

mpm_winnt:error AH00326: Server ran out of threads to serve requests. Consider raising the ThreadsPerChild setting

we have hide all below settings

#EnableMMAP off
#EnableSendfile off
#Include conf/extra/httpd-mpm.conf in apache conf file

I have mentioned below code in top of the conf file

AcceptFilter http none
AcceptFilter https none

This was worked. Server working fine but now days again this issue is started.

Still I am getting the above error. Can you please help me what is the exact problem ?

at the moment you have

<IfModule mpm_winnt_module>
ThreadsPerChild 150
MaxRequestsPerChild 0
</IfModule>

you simply increase that number Wink and don't forget to restart apache.

That is not an apache problem, but your database needs a tuning.

in your mysql config file

use query cache!

like
Code:
query_cache_type = ON
query_cache_limit       = 256M
query_cache_size        = 256M
join_buffer_size        = 8M

Hi James,

Thanks for your help.

We rebooted our main server before 2 weeks ago. It is running smoothly. but now day (this week) when I have checked in middle of day it is taking some time to open.


As per your suggestion, I have added this in mysql config file (27 DEC 2016) and then restarted mySQL and Apache server.

I will keep watching on this.

I will let you know if anything is observed .

Thanks,
Swapnil
