Defender Fix issues : server resource usage is too close to your limit.

Morning team,

When using defender, have run a scan and got 28 issues, when i click on Fix i get a red error box ” Your server resource usage is too close to your limit. Please try again in 15 minutes.” I’ve been trying for last 1hr.

Thanks

Alex

Hi Alex Barrett,

Hope you are doing good today :slight_smile:

Its because the CPU usage is too high and hit the maximum limit. You can increase the limit by adding following code in functions.php file of your theme or using it as mu-plugin.
```
add_filter( 'wd_limit_cpu', 'wd_limit_cpu' );

function wd_limit_cpu() {

return 1;

}
```
Hope that helps! Feel free to post a reply if you need further assistance :slight_smile:

Cheers, Sajid

What I’m doing where here?

<?php

/*

add_filter( 'wd_limit_cpu', 'wd_limit_cpu' );

return 1;

}



?>

The plugin is loaded, but take no effect. So something must be wrong in my code. Thanks in advance for your answer.

DreamQuest,

Perhaps the 1 is not the correct value.

Please visit here

And check the CPU usage, if that is 0.xx, then 1 is fine. However, if that is larger than 1, for example 4.55, then you need to increase it to 6 or 7. I assumed the right value is 7, so your code should looks like this

I’ve done this one about 15 sites now and have Defender Successfully run it’s first Scan. I’v had to on average put it to “20”.

Hmm that is interesting indeed!

My CPU value was as you wrote a lot higher indeed.

Thanks for pointing this out! @webexperts09!!

I can now also successfully confirm, that my little MU plugin that I wrote (thanks for the corrections Hoang Ngo :slight_smile: ) does indeed work now with awesomeness! :smiley:

BTW for those that use WMPU and not standalone version of WP, the url is different!

Yikes!

It seems that I was wayyy to fast on the “green light trigger”.

The code does work on my smaller WPMU site, but on my large live/production WPMY site, I get WSOD and so far i don’t have any ideas why this is happening. If i delete my MU plugin from the site, it sings happily again without any issues.

So close, so…. “fire, but no cigar”

In defense of my little plugin code, must though say that my live site is waaay more complex. So maybe it is not the MU plugin itself that “fails”

Great advice!

I went to check my CPU usage according to this instruction and it was 7.76

I paced the “return” value to 12 according to Hoang’s instruction into the functions.php file of my theme and it is working now.

Thank you!

How do you rate me?
