There are 3 servers:

  1. DB Mysql;
  2. Client part (website);
  3. Serves installed extensions (High loaded).

This afternoon, on the 2nd server (site), an error appeared connecting to the database server ( Can't connect to MySQL server on ). In this case, the third server connects to the database stably!

I just can not understand what's the matter! Increased max_connection to 1000, prescribed permissions in iptables , all the same, the third server always connects to the database, and the second one times.

I really need help, a project on production ...
