xcache is not working. What to do?

Question

PHP

Hello!
The server has the following configuration: nginx + php-fpm + xcache + mysql.
All this is spinning under the Ubuntu server.
phpinfo() shows that xcache is up and running. There is also an xcache panel that shows how much data is in the cache memory. At a certain point in time, I noticed that sql queries that should not be processed because for some reason, the data from them is cached and continues to be densely poured into mysql.log. What could it be and what solutions are there?

Answer 1

And the problem is not in the application caching layer?

Answer 2

UPD: You need to add custom validation through hook_form_FORM_ID_alter(), in which you check the role of the account whose password you want to restore and if it is "Operator", then return an error.
In your case hook_form_user_pass_alter()
