[jira] [Reopened] (KAFKA-3702) SslTransportLayer.close() does not shutdown gracefully

["Rajini Sivaram (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/KAFKA-3702?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rajini Sivaram reopened KAFKA-3702:
-----------------------------------

We changed the log level of the entry `Failed to send SSL Close message` from WARN to DEBUG, but we haven't yet fixed the underlying issue. At the moment, we attempt to flush all outgoing data and close gracefully, but disconnect if we can't do so immediately. Reopening the JIRA to track the underlying issue.

> The warning "Failed to send SSL Close message" occurs very frequently when SSL connections are closed. Close should write outbound data and shutdown gracefully.
