Memory allocation limit in vBulletin

[toadtje]

Hello.

Getting this error in vBulletin:

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 90000805 bytes) in /home/tommy/forum/includes/class_core.php on line 1806

To explain, I am trying to upload a 90mb attachment to my forum (its a sharing forum for video files).

The php.ini config I use in order to allow for bigger uploads are:

max_execution_time = 120 ; Maximum execution time of each script, in seconds
max_input_time = 60 ; Maximum amount of time each script may spend parsing request data
memory_limit = 256M ; Maximum amount of memory a script may consume (16MB)
upload_max_filesize = 200M ; Maximum allowed size for uploaded files

Also, attachments are in file system not in database.

And I run vBulletin 3.6.8

Any hints as to getting rid of the memory allocation error above?

I appreciate any help

Kind regards
Tommy

Basically, the script wants more memory.

Yeah I gathered that much.

But it shouldnt be necessary to raise the memory limit any further, should it? Its already at 256M.
