High memory usage caused by too many /usr/bin/php processes

attiliok
Hi, I have a dedicated server with 50 or 60 accounts on it. Load averages are good, but memory usage is very high and it's caused by lots of /usr/bin/php processes opened (almost 100). I think they are not really running, they probably are zombie processes that are not terminated. If I kill all those processes, or if I restart apache, memory come back to normal, but just for a while. After some minutes it start to grow more and more as you can see later. I have read everything on this and others forums about mem usage and high server load and those seem the options: Option 1) Those are zombie processes and the system for some bug is not able to terminate them. Update easy apache, recompile php, and see if it still happens. Option 2) Those are zombie processes, so create a script that kill all zombie php processes every half hour to solve the problem. Option 3) Those are note zombie processes, the problem is elsewhere! So, please, if you think that option 1 is the correct one, do you really think that i should update easy apache? Is'nt it actually a dangerous operation? If the update/recompile fail, will my websites go down? If you think that option 2 is the right one, can you help me find a way to write a script to accomplish the mentioned task (killing zombie php processes)? Otherwise, what's the problem for you experience? Here all the information needed. Thanks in advance for your time. SERVER INFOS

    Hello, There is no harm with option one. Easyapache update process backup apache directory and restore itself if apache+php compile fails. This generally takes around 30-40 mins. Just make sure you don't restart apache service or server when easyapache update is in process. Even if server reboots or apache service restarts, don't worry data is already backup so but in this case you will need to restore it manually. Regarding zombie processes are you sure those are zombie processes ? You can find zombie processes by executing commands ps aux |grep "defunct" ps aux |grep Z In case of zombie we need to find out parent process using command pstree but I think it will hard to trace parent process and then kill that. Instead I would recommend to restart apache service which will definitely kill zombie processes. 3rd. I think this is not zombie processes issue. It could be just bad code which cause php processes using high memory. You can find processes using high memory in ascending order using following command. ps aux --sort -rss Once you get process ID use command ls -l /proc/PID-Here. Regards, Sagar

    First off all, thanks. So I can tell they ARE NOT zombie processes. The commands you suggested me stats clearly they are not. But I'm also quite sure that my problem is not a bad code of a single site. In fact I have many /usr/bin/php processes for almost everyone of my site. Look at the full page result I attach here, it will be more clear.

    Hello, There are lots of php processes running but they doesn't belong to specific site. Also memory usage of individual php script also seems fine. If sites hosted on server are loading with normal speed then I think you just need to add more RAM. I don't see any issue other than this.

    Thanks again for the good news. Just one question: many of those processes are running, but, as i can see from apache status, there is nobody visiting the sites related to the processes. Is it normal? Should'nt they be terminated by apache after being used? Or, if you think that they are currently working, how can I now WHO or WICH PAGE is using the process that seem idle to me and to "apache status"?

    Hello, It's hard to tell/predict what could be going on that server. It is possible when single user access one site and php code of index page is designed in such way to execute multiple scripts from that account.. Also many times php codes execute DB query which could execute other php script to generate output to web user. Are these CMS sites like wordpress ? btw, you can check process details with command ls -l /proc/7158 here 7158 is process ID from command output you provided in second post. site1 7158 0.7 1.0 227860 82196 ?

    Hello, While slightly unrelated to this topic, I did want to make note of the following thread: Troubleshooting high server loads on Linux servers It's useful to review when troubleshooting overall CPU/Memory issues on a system. Thank you.

    I'm still investigating thanks to your answer... As you suggested I typed the ls -l proc command but it didn't help me, I cannot find information that help me understand what's happening. I have many wordpress sites, but many of the processes that run and never terminate are not CMS or Wordpress. As for the link suggested... Thanks! I know that post very well, but it doesn't seem to help. Thanks again

    I solved the problem switching from fcgi to suphp. WITH FCGI i had: one hundred of php process always running, 80% of ram used WITH SUPHP i have: one ore two php process runnning, 27% of ram used. I think FCGI, in my case, had a bug (also mentioned in other posts by other users). Thanks for your help. Attilio
