There are two vbulletin forums hosted on my colocated, Q6600 Quad Core, 4GB RAM server and this process [php] <defunct> keeps spawning constantly and hogging the CPU resources.
Each process lasts a matter of seconds and dies but it keeps spawning itself constantly. Heres a screenshot:

Ive tried restarting Apache but it doesn't solve it.
the requist top in SSH it give everyday:
Code:
1869 johnhost 15 0 0 0 0 Z 8 0.0 0:00.25 php <defunct>
1871 johnhost 20 0 0 0 0 Z 8 0.0 0:00.25 php <defunct>
On my server, i have one user ho create load on my server.
user 29508 22.0 0.0 0 0 ? Z 15:18 0:00 [php] <defunct>
That user has more site added with addons from cpanel. How can I found witch site is generating that high load ? Also some time, I have php index.php ( and that don't help me very much )
The server run php as cgi module.
I've had a shared hosting account for several years and never had this problem before. Since yesterday I occasionally get 500 internal server errors on all my websites simultaneously due to a large number of processes on my account. When I log into cPanel and click on View Processes I only see 1 or 2 at a time, but support tells me that there are actually more than 25 processes and this is not allowed.
Apparently they are defunct PHP processes (zombies?) that are waiting on their 'parent' processes to clean them up and for some reason my account is accumulating a lot of these.
Support is not able to tell me which of my PHP scripts is causing this. All they can give me is something like this:
USERNAME 4541 0.0 0.0 0 0 ? ZN 18:25 0:00 [php] <defunct>
USERNAME 4828 0.0 0.0 0 0 ? ZN 18:25 0:00 [php] <defunct>
USERNAME 5114 0.0 0.0 0 0 ? ZN 18:26 0:00 [php] <defunct>
USERNAME 5265 0.0 0.0 0 0 ? ZN 18:26 0:00 [php] <defunct>
...etc
I have several websites on the account that use my own written PHP. I especially use a lot of functions related to mySQL, simplexml_load_file and reading/writing cache files. I don't know where to start looking to find the PHP that is causing these defunct processes.
My server is overloading badly
The top processes are :

How do I fix it out, I've Core 2 Quad with 2 GB ram...
I've 50 sites hosted on server all are small sites, not more than 20 users online on a site
still box overloads, I've 4 GB ram, and load sometimes reaches 160, 200 etc
My server has been running slow for a while now but I was out of twon so I was not able to check on it. I just got back and find that the server load is above 4.50 for a dual cpu server with 2GB ram. I have looked and all I can see is that there are a few sites using a good amount of resources. However, on my other server, I have sites that are even more busy then the ones on the server that is overloading. I cannot seem to find what is going on or what to do about it. Please help me. The sites are moving at a snails pace.

I know there's been discussion regarding Foundry BigIron's and their capabilities of running L3 and L2 at the same time.
I have a friend who is running a BigIron 8000 and only pushing just over 100Megabits on it, however once every few hours he experiences a BGP flap and one of the CPU's maxes out. He is running both Layer 3 and Layer 2 on it.
When the issue occur's, new connections do not open, but currently opened connections continue to operate.
Is there a specific packet type that is causing this to happen? Does anyone have any insight? It is running the latest firmware.
I currently have a web VPS hosted with FDCServers.net and after 5 days of switching to it i am getting massive HTTP requests. When i login to WHM and hit apache status i have many requests per second by multiple IP's that are going to pages that simple don't exist. Currently my hostname for the server is set at web-01.optical-hosting.com which is what the requests are being sent to. I am also having a DNS issue because when i put http://web-01.optical-hosting.com in the web browser it displays the first account's site under "list accounts" in cpanel. Can someone please help me fix both of these issue's? i will post an apache log in a second post as it is long. Also, these are from overseas. please someone help me with this i have Aim and Msn.
View 4 Replies View RelatedMy host has suspended saying my server was overloaded and sent me a log to my mail and i don't have access to cpanel also. I just have a wordpress blog and when i had contacted host through chat they told some ip might be causing this issue so ban that ip when ur account is unsuspended.
But i am really unaware of how to find which ip is causing this issue as i have little knowledge on analysing logs. Any help regarding this is highly appreciated and please leave your suggestions for me.
I am pasting the logs that were sent by host to me in mail:
