Out of memory problems [message #10639]

I only have one VPS on the box. I used vzsplit 1 to make the config file so it should have all the resources of the box. However I'm running into a ton of "memory" problems;

Here is a "top" of the node;

Cpu(s): 3.0% us, 3.3% sy, 0.0% ni, 92.8% id, 0.0% wa, 0.0% hi, 1.0% si
Mem: 1023728k total, 448488k used, 575240k free, 38032k buffers
Swap: 2048276k total, 0k used, 2048276k free, 134688k cached

Here is a "top" of the VZ;

Cpu(s): 11.1% us, 3.2% sy, 0.0% ni, 85.5% id, 0.3% wa, 0.0% hi, 0.0% si
Mem: 1023728k total, 227320k used, 796408k free, 0k buffers
Swap: 0k total, 0k used, 0k free, 0k cached

[client 68.98.x.x] PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 11264 bytes) in /var/www/html/wm.php on line 47

Here's a list of my bean_counters;

This has nothing to do with openvz- this is a limitation in your php environment. To verify:

grep memory_limit /path/to/php.ini # (usually /etc/php.ini)

You will see something like this:

memory_limit = 8M ; Maximum amount of memory a script may consume (8MB)

Increase 8M to 64M or whatever your php script needs and restart apache.

Sorry, should have clarified better.

I also get the same memory problems on bash.

do you mean when you launch a php script with a bash shell? Yes, this makes sense. Rolling Eyes

Use my reccomendation, it will fix your problem.

you are getting a php fatal error from ps?- I really doubt this. I think you are not providing adequate information about your problem, or you just plain don't understand how to interpret what is going on.

Nevermind -- obviously you are clueless.

I'll fix the problem myself.

Hi,

> "When I am in bash, and I type ps aux, I get the SAME memory problems"

You have no increased failcounters of kmemsize, privvmpages, shmpages or related memory parameters in /proc/user_beancouters,
are you sure that's an OpenVZ "out of memory" error not php ?

Can you please, post
- the error message inside bash
- relevant memory info's of used php.ini

Sure thing. When I get it again, I'll paste it here.

However it was something like 'Cannot Fork -- Not enough memory' when I did simple commands such as 'ps', 'aux', etc.

However I was still able to do them in the hardware node.

I was under the impression that since I ran vzsplit 1, it would use all the resources on the hardware node. Therefore if vps 1 cant do a ps aux due to memory, the hardware node shouldn't either but that wasn't the case.

Hence why I posted a question about it here.
