The mysql client likes to read table names and column names on startup to enable autocompletion:
> mysql -h"some_url"
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
If one of the tables it reads contains a hyphen, for example test-table then the following query fails to be parsed.
SELECT*from test-table LIMIT0;
This causes the mysql client to think the connection was dropped.

# separately> mysql -h"127.0.0.1" -u"root"
