    Description

      If the client sends very large amounts of data and the backend writeq_high_water is hit, the client is removed from epoll until the backend buffers fall under writeq_low_water. During this time if a backend sends a response, it is discarded by the backend protocol code. This can manifest itself as a hang during large batch uploads using the MariaDB JDBC or Nodejs connectors.
