ArrowChat

After Update & complete new Installation of Arrowchat 3.0.5 i have recognized higher cpu usage on my apache server. When I look into it (mod_status) i recognized it comes from:
/arrowchat/includes/json/receive/receive_core.php
These process takes now slightly longer to process.
Does anyone else recognizes this behavior?

Fixed, memory leak in php7.4.8...
With php7.3 it works without a problem :)
