Ask questionsshutdown ENOTCONN on TLS.Socket._final
When using v10.15.1 we are seeing processes exiting with:
Error: shutdown ENOTCONN File "net.js", line 364, col 25, in TLSSocket.Socket._final File "_stream_writable.js", line 612, col 10, in callFinal File "internal/process/next_tick.js", line 63, col 19, in process._tickCallback
This appears in services connecting to Amazon RDS instances via TLS. We are using https://registry.npmjs.org/mysql/-/mysql-2.15.0.tgz and https://registry.npmjs.org/knex/-/knex-0.14.4.tgz for connection pooling.
We do not see these errors on earlier node image (I have tested v10.15.0, v10.14.2 and v10.0.0).
Could this be impacted by #24290 and related commits?
The errors could possibly be bettered handled higher up (by knex or the mysql client), but this does seem to be a significant change in behaviour.

We're running into the same issue. I don't have a fully runnable repro that I can share, but it reproduces when the connection is closed while the query is still in flight. It looks roughly like this:
const connection = mysql.createConnection(...); await connection.connect(); connection.query('SOME QUERY', ); // Important: missing await await util.setTimeoutAsync(100 * Math.random()); // wait a bit; not sure if this is necessary. connection.end();
There is just email@example.com, no pooling.
