suhosin[4652]: ALERT – script tried to increase memory_limit to 268435456 bytes

Hi

I have been trying to fix an error showing on my shared host log files.

suhosin[4652]: ALERT - script tried to increase memory_limit to 268435456 bytes which is above the allowed value (attacker 'xx.xx.xx.xx.', file 'example.com/wp-admin/admin.php', line 109)

Its my IP and happens when i log on to wp-admin

I have done some reading around this and just cant seem to find a definitive answer or best way to approach.

I do have a few WP sites on the same server. I have 10 MB memory

I did try to lower a memory limit on 1 site within the WP files a few weeks ago, but can not for the life of me remember which file or where i read it. Sorry.

Changing the limit did seem to work, but after WP update i think the changes have been overridden

I am getting OOM errors could this be related?

My php.ini file is

; Maximum amount of memory a script may consume (128MB)
; https://php.net/memory-limit
memory_limit = 128M
