php fatal errors memory etc.

[travbacon]

version 1.5.7.c, the latest

Request URI: /index.php?reviews_id=541, IP address: 157.55.39.20
PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 16384 bytes) in /var/www/vhosts/domain.com/httpdocs/includes/classes/db/mysql/query_factory.php on line 44.

I have looked in my log and have cleared every php error log that is possible. the only remaining ones are these that keep popping up. i know it is more of a server issue but could someone possibly point me in the right direction? the URLs vary. this is just an example when someone i guess goes to a url and then the error is next.

Increase this:
> PHP Memory Limit: 128M

Set it to 1024M at least.

[travbacon]

Should I double it?

Are you looking at your traffic and making sure you're not getting overwhelmed by junk and spiders?

[travbacon]

I'm getting stupid stuff like this constantly all different from different ips. i am adding to .htaccess constantly which helps

order allow,deny
deny from 173.218.127.89
deny from 173.218.127.89
deny from 173.218.127.89
deny from 173.218.127.89
deny from 173.218.127.89
deny from 173.218.127.89
deny from 173.218.127.89
allow from all

http://www.domain.com/category-c-290...xslider.min.js (this is an example)

i don't know any other way of blocking these ips

[swguy]

You might want to talk with your hoster to see if they offer country level blocking.

[travbacon]

oops edited, wrong reply

[travbacon]

for future reference those looking i found this

https://www.ip2location.com/free/visitor-blocker

you can enter the country and it will generate the block deny whatever so you can add it to your htaccess file

i am going to start with the chinese commies
