MySQL, which recently restarted the server, always reported a large number of errors such as: 


160330  9:14:26 [Warning] /usr/libexec/mysqld: Forcing close of thread 139  user: ‘root‘
160330  9:14:26 [Warning] /usr/libexec/mysqld: Forcing close of thread 138  user: ‘root‘
160330  9:14:26 [Warning] /usr/libexec/mysqld: Forcing close of thread 137  user: ‘root‘

160330  9:14:26 [Warning] /usr/libexec/mysqld: Forcing close of thread 130  user: ‘csm‘

This error is actually MySQL in the DNS to do counter-check, due to the continued speed of the counter check too slow, a large number of query processing is not timely, the thread is not released, resulting in MySQL "Suspended animation."

Skip-name-resolve

Windows Server
