PHP Fatal error: Out of memory (Apache crash)

Hi:
I am trying to find a solution for this error that consequentially leads to Apache Server crash.
Following is the message as seen in the error.log file:
PHP Fatal error: Out of memory (allocated 786432) (tried to allocate 32768 bytes)

SERVER CHARACTERISTICS:

* Windows 2008 Enterprise Server
* PHP 5.2.6
* Apache/2.2.4 (Win32) DAV/2 mod_ssl/2.2.4 OpenSSL/0.9.8e
* RAM=8gb,

PHP SERVER PARAMETERS:

* max_execution_time = 720
* max_input_time = 360
* memory_limit = 5120 MB

After a few messages like this, the server ends with the message:
[notice] Parent: child process exited with status 255 -- Restarting.

Whenever it happens, I don't see a substantial rise in memory usage (well under the 5GB established in the configuration)
I think part of the problem is originated because the server is not releasing memory, and the data is adding-up.
It is surely a misconfiguration of my server
I have searched everywhere but didn't found a satisfying solution.

Thanks for your help.

 

How much is the server ram .. it needs a increase

 

Thanks,
Maybe, It has only 8 GBytes, how much do I need, I think the limit fo my harware is 32GBytes

 

Depends on the site hosted on the server.. Try optimizing things

 

It is a dedicated server, only Apache/PHP, for my single application, the database is on another one.
There are only 5 users! tha capacity should be at least 200 users?
It is possible to see the code of the actual script being executed?
The server works well for some hours, and after a while, it starts to log error messages:
PHP Fatal error: Out of memory (allocated 6291456) (tried to allocate 393216 bytes) in...
the quantity showed is variable.
After 5-6 messages the server shuts-down with the following message:
Parent: child process exited with status 1 -- Restarting.

 

The error "PHP Fatal error: Out of memory" is most likely related to memory_limit. If your script is trying to using more than allocated limit in memory_limit in php.ini, you will receive this error. Upload phpinfo page to your domain and verify that you have allocated sufficient value in php.ini. Do not forget to restart Apache after changing the value.

Kailash

 

Are you running suexec or suphp on the server?

 

i think the
memory_limit = 5120 MB
is set up to high
i once had problems with values over 900 megabyte
also you most likely will never need such high ram for single php scripts.

set this value to something like 800 mb and try again


the error message says a lot of strange things

786432 bytes is only ~800 kilobytes, 32768 bytes is only 32 kilobytes.
if your server troubles at these low values, it is simply misconfigured.

dont use extreme values in php.ini

 

Thanks
I've already raised memory_limit up to 5120M but it seems Apache or PHP doesn't recognize such a large value because my Apache server crashes at about 2500MB of memory usage (of a total of 8GB available in RAM)

 

Thanks,
I have done, and will see if it helps.
I think Apache is NOT RELEASING memory at a sufficient rate and it is BUILDING-UP.
Is there any parameter I can adjust for this purpose?

 

Thanks,
No, I'm using only the XAMPP distribution
