frequent "got an error writing communication packets"

[Alberto Pastore]

I'm not sure where to post this problem, since I have no idea if it's a client prroblem or server problem.

On some Mysql 8.0.x instances (x ranging from 25 to 38) I get frequent errors from client connections, reporting the message "got an error writing communication packets".

Is it not a network issue.

The problem occurs for instance even locally using mysql command line client via unix socket:

```
root@inim-db-repl:~# mysql my -e 'show table status'
ERROR 1160 (08S01) at line 1: Got an error writing communication packets
root@inim-db-repl:~#
```

The inim-db-repl is a replica server for a database named "my".

This error occurs randomly even on low-load test servers, no matter which client is trying to query the database (php, python, c#) or which query is executed (event ultra-light simple queries).

I've been googling around for months and I'm clueless.

Nothing meaningful is shown in mysql server error log.

Any hint?
