Fatal error: Allowed memory

[Newbe]

Hi, this is the error i get in my pligg site. It's an open source script. I have no idea about php, so can anyone help me please?

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 41418752 bytes) in /home/tarok/add-article.info/libs/ez_sql_core.php on line 374

This is the link 374

$result_cache = unserialize(file_get_contents($cache_file));

Problem appeared after my host installed PHP 5.2.8 (from PHP 5.2.7)

[ScriptMan]

Your script used all the available memory. This is a setting in the Apache and php files. Most likely nothing you can over ride. Perhaps the host had Max_memory set higher under the old version.

You might ask them to take a look if the script worked before.

thanks, i sent them an email

Upgrade your memory limit... average is 16mb-32mb

[Newbe]

how do i do that? is this to do on a script or on server

[Izzmo]

Sometimes, if your host allows it, you can override this in a .htaccess file like:

php_flag memory_limit "8M"

If not, your host may able to give you a custom php.ini file for your site.

they have managed to fix the problem

How did you fix it?

They probably increased the limit on server-side. However, for future references you could try ini_set() command to overrride the setting in php.ini.

[Newbe]

ok tny

i will try that

and sory, i have no idea how they fixed it

[dWhite]

If you need more help on the ini_set() command, check out the official php.net listing of it:

http://us2.php.net/ini_set

You would use it like this:

ini_set('memory_limit', '50M');

Replace the 50 with however many MB you need to for the script to allocate.

[Newbe]

that's great info!

thank you my friend

That or like I said previously, .htaccess php_flag measures work well.

Ok the error is back...

what does this actually means?

now it wants even more memory:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 133693440 bytes) in /home/tarok/add-article.info/libs/ez_sql_core.php on line 374

Is this memory space on disc? or operative memory? why is it growing like this?

i have tried the htaccess thingy, but don't knoe where to put the ini_set('memory_limit', '50M');

[ScriptMan]

It might be a poorly written script causing the problem.

Does this problem occur only after some of the script features have been used a few time? Some script writers fail to destroy images and close mysql connections both of which can tie up memory.

[Izzmo]

Well, your host is only allowing you so much RAM to processes PHP functions and go throughout your script.

So, if you go over that, the script is haulted and you get this error.

What are you trying to do, image manipulation?

[Newbe]

it's an open source digg like script called pligg

i have no idea what was going on and i am not doing anything...

i have no idea what is wrong :$ what should i do?

[Izzmo]

Well, from the error, it may be doing something with SQL queries.

Maybe it's trying to execute too many queries at once? It's hard to say without actually looking at the code itself.

But I'm pretty sure, from the error anyways, it's calling queries and then trying to process a bunch of them at once.
