Connection issues with DBs inside Docker on Linux

[sj14]

After enough iteration, the connection gets unintentionally closed. Might be a Docker bug on Linux.

MySQL and MariaDB

[mysql] 2018/12/16 14:33:08 packets.go:36: unexpected EOF
2018/12/16 14:33:08 INSERT INTO dbbench.simple (id, balance) VALUES( 9458, 3611810842); failed: driver: bad connection

PostgreSQL

2018/12/16 13:53:19 DELETE FROM dbbench.simple WHERE id = 56669; failed: read tcp 127.0.0.1:42836->127.0.0.1:5432: read: connection reset by peer

I'm facing similar issues when increasing the iteration number. Encountering issues on both on our k3s cluster and when running inside docker.
