Fatal error: Allowed memory size exhausted

FULL ERROR IN BROWSER:

Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 107962344 bytes) in /usr/local/www/classes/Form/Section.class.php on line 134 PHP ERROR: Type: 1, File: /usr/local/www/classes/Form/Section.class.php, Line: 134, Message: Allowed memory size of 536870912 bytes exhausted (tried to allocate 107962344 bytes)

• First things first 536,870,912 bytes is bigger than the attempted allocation of 107,962,344

• This happens when I attempt to edit an alias that got imported fine but cannot be edited now since it has thousands of lines of CIDR networks. Idea is to block traffic from countries with many nefarious actors.

• I read somewhere such config can cause a hard crash so I have not implemented the aliases into rules, only created them. But if it crashes while trying to edit the name, I would be hesitant to make rules to process those aliases.

• Referenced line 134 is <scope>user</scope> so I'm obviously looking at the line count wrong.

@peterlecki If you're using very large aliases then you may have to increase your Firewall Maximum Table Entries via System - Advanced - Firewall & NAT.

That is probably the global 512MB PHP memory limit you're hitting. Other things are already using it when you try to open the alias requiring an additional 100MB. The maximum table size value probably isn't going to help there.

Basically if you're seeing that you're are probably using the wrong alias type. Aliases that large should be imported URL aliases. pfBlocker was designed to solve exactly this problem. I would be using that.

Thanks, @stephenw10
Maximum Table Entries made no difference, as you expected. I will try pfBlocker right now.
