Php Script Causing Too Many Simultaneous Connections.

[compixtr]

hi everyone.

 

i have a strange problem, i have a client running a very simple php script on my server which is somehow causing a really high load and making server unresponsive by creating hundreds of simultaneous connections. (i see lots of php processes under this user and i see hundreds of incoming connections from server to itself again as if the script is causing a loop?)

 

i am not a php expert. but when i look at his script it seems as if it's acting like a proxy, that should try to connect a remote server to retrieve something.

 

when i look at the error log in the same directory i just see the errors below and i couldn't understand what this error exactly means?

....

 

anyone have any idea about how to track down this issue? i almost checked all web server-php related logs but could not find anything.

 

thanks!

Is there more to the log messages than you're posting? What you've posted isn't enough to determine what's happening.

 

Only thing we can say now is that the 302 probably means the script redirected someplace.

the log file is quite long. i've just checked the whole file and found two more error types as below;
