    Hi,
    I’ve enabled Page cache , I guess it works well.
    But when I purge page cache, a lot of error logs would be generated(about 74 error logs in 10 minutes) , and it also caused my website(hosted in CLOUDWAYS) down.

    Those error logs are like:
    [Tue Jan 19 19:19:20.007632 2021] [proxy_fcgi:error] [pid 29653:tid 140050838685440] [client 2400:8902::f03c:92ff:fe2c:a1f4:57354] AH01071: Got error 'PHP message: PHP Warning: Error while sending QUERY packet.

    Hi @unbosomjam,

    Thank you for contacting us.

    Sorry to hear about the trouble you are having. Doing a quick search online, the errors are related with your current server configuration from your host provider. On the database packet, error pertains to a site having a number of database requests limitation within the database causing not to make a connection. The connection errors possibly all related to your Fast CGI application module set on the server.

    Please contact your host provider to verify your current database queries and check why there could be limitation with them. You can also install a plugin called query monitor(free WordPress plugin) where you will be able to verify which queries are slowing down the site.

    Best,
    Jonathan S
