Several httpd are running

[vishnukumar]

Hi,

I am facing a problem with httpd. I found, several httpd are running, when I use this command ps –e. I got

5779 ? 00:00:00 httpd
25780 ? 00:00:00 httpd
25785 ? 00:00:00 httpd
25792 ? 00:00:00 httpd
25793 ? 00:00:00 httpd
25794 ? 00:00:00 httpd
25795 ? 00:00:00 httpd
25798 ? 00:00:00 httpd
25803 ? 00:00:00 httpd
25806 ? 00:00:00 httpd
25807 ? 00:00:00 httpd
25808 ? 00:00:00 httpd
25839 ? 00:00:00 httpd
25844 ? 00:00:00 httpd
25845 ? 00:00:00 sshd
25849 ? 00:00:00 sshd
25850 pts/0 00:00:00 bash

25900 pts/0 00:00:00 strace
25905 pts/0 00:00:00 ps
27568 ? 00:00:17 java

Above I have listed less. But, I got more than 80 httpd are running. And, then I use strace and got

strace -p 25785
attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted

But, when I try another as

strace -p 25806
Process 25806 attached - interrupt to quit

I am new to linux. I have fewer users to my website. But, the bandwidth usage is very high, I think, it’s due to several httpd. I am using apache-tomcat-5.5.27 and red hat enterprise linux 5 ES. I don’t know how to minimize no. of httpd running on my server.

Thank you

It is normal to get multiple apache (httpd) processes running. You will get one for each concurrent request.

You can set the limits by editing the appropriate information in /etc/httpd/conf/httpd.conf and restarting the service.

Hi,
Thank you for your reply. The bandwidth usage of the website is 1367396 GB. I know it’s very high. I have a log, which shows, only 38 visits. But, how this visits makes higher bandwidth usage. I didn’t meet this as before. As I saw in the services, I blame on httpd daemons.

Please, help me to detect, why this higher bandwidth is occurred and why it’s continuing?

Thank you
