Can't create a new thread (errno 12) Solution

Error No:1135

Problem Analysis:

Due to database server problems, a new thread cannot be created for database operations. There are two possible reasons:

1. MySQL threads are too open.

2. The server system memory overflows.

3. damaged environment software or system.

Solution:

1. For VM users, contact the Space Provider to check whether the memory and system of the database server are running properly.

2. Independent host users:

1) enter the user table in the mysql database of phpmyadmin, edit the database user, and modify the value of max_connections. Change it to a smaller value.

2) contact the server administrator to check whether the server memory and system are normal. If the server memory is insufficient, check which processes consume the server memory, at the same time, consider whether to increase the server memory to improve the load capacity of the entire system.
