Re: ERROR 2013 (HY000): Lost connection to MySQL server at 'reading authorization packet', system error: 95

Interesting. It was pulling it from the plugin director.
I asked my sys admin to remove it. He said he would need to get with me later but that auditd was using it. ?? So I switched over to another sandbox server that did not have the server_audit.so file in the plugin directory. I got a loading error, but at least the client connected normally. Here is the error in /var/log/mysqld.log on the second sandbox server:

2022-04-05T17:56:40.802181Z 0 [ERROR] Can't open shared library '/usr/lib64/mysql/plugin/server_audit.so' (errno: 2 /usr/lib64/mysql/plugin/server_audit.so: cannot open shared object file: No such file or directory)
2022-04-05T17:56:40.802223Z 0 [Warning] Couldn't load plugin named 'server_audit' with soname 'server_audit.so'.

So, it would appear that mysqld looks for this plugin. If it doesn't find it in versions 5.7.34 or above, that is a good thing. In version 5.7.33 the plugin loads and works well.
