Memory Errors

[ducey]

Hi,

I have a PHP script that analyses the access log that Apache creates and I have started to receive memory allocation errors.

As far as I know, nothing has been changed on the Linux server (RedHat 8) that it is running from, but the script runs for a few seconds then the following error is returned:

<b>Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 1025 bytes) in /usr/local/www/analyse/fileanalyse.php on line 21</b>

Does anyone know what this means and how it can be fixed please? As I haven't a clue! 🙂

Many thanks,
Nathan

Hi,

there is a setting in php.ini called memory_limit. This is set to 8M per default. If your scripts needs a lot of memory (big array or something like that) you might need to increase that value to e.g. 80M or whatever you need. A better approach would be to check if your script can be optimized in some way so that it doesn't use that much memory.

hi,
you must be trying to read the whole apache log file in to memory and then trying to parse it. if thats the case then i would recommend u to read it line by line. The reason you are getting this error is because you are using lots of memory

Hope this helps

Hi Thomas,

Thanks for your reply 🙂 I have changed the value of the memory limit, how do I make these changes effective? Do i reboot my server or just Apache?

Thanks for the help!

Hi Koolkrazy, thats a good suggestion. I never thought of doing it that way.

Thanks for that. I think I need to re-write my script now!! 😃

Thanks again,
Nathan
