• **dble version：3.22.0.1
• **mysql version：5.7.37(m) 8.0.27(s)
• preconditions ：
  在该版本的dble中，只使用读写分离功能，链接到9066之后，use 管理库，会触发重连。

1. we don't have dble versio of 3.22.0.1，and has tried to reproduce with two dble version：3.22.01.0 && 3.22.01.1 failed，if you used other dble version come across this issue，ple let us know
2. pls provide your mysql-client version【the tool used to connect dble】、fakeMySQLVersion in bootstrap.cnf
3. better to provide dble.log with debug log level when you reproduce this issue
