Hi @vince992001,
Due to the volume of topics that can be created each week, if a topic goes without response for over 7 days they can be hard to keep track of as new responses don’t rise to the top of the listings. Thanks for getting in touch again with a diagnostic and screenshot of your emails.
It is most likely here that the page requests came in very fast, and hits being processed in parallel caused the multiple emails. Basically, hit 1 sees the IP is not blocked, hit 2 sees the IP is not blocked, hit 3 sees the IP is not blocked, then hits 1, 2, and 3 all decide to block it because it hit the limit, and all 3 send their emails. From that point forward, it’s blocked, even if more hits come in, as long as the hit started after at least one of them blocked it.
This can still occur on faster servers, which could mean the database is the slowest element of each transaction, or the server is just configured to process more hits in parallel.
max_execution_time in your php.ini could be changed to the 60 we recommend as higher numbers can cause issues, and wp_memory_limit in wp-config.php should be set to 128M or 256M instead of the current 40M (default). Your PHP memory_limit value already looks be large enough to accommodate this change. You could always give that a try and see if the blocks are quicker to take effect.
Thanks,
Peter.
