refresh/reload loop of version 2.4.0

Hi Guys

Found that this snippet that i use is the cause of the constant refresh/reload loop in version 2.4.0

Obviously I need this on the 20+ sites as every day the cache on some now climbs to over 2GB in a day now i cant use in 2.4.0

if (class_exists('autoptimizeCache')) {
    $myMaxSize = 256000; # You may change this value to lower like 100000 for 100MB if you have limited server space
    $statArr=autoptimizeCache::stats(); 
    $cacheSize=round($statArr[1]/1024);
     
    if ($cacheSize>$myMaxSize){
       autoptimizeCache::clearall();
       header("Refresh:0"); # Refresh the page so that autoptimize can create new cache files and it does breaks the page after clearall.
    }
}

Any ideas on what i need to change?

Cheers
