Subject Re: Large value of idleConnectionTimeout in TcpCommunicationSpi
Date Wed, 19 Jul 2017 21:30:44 GMT

Default idle timeout is actually 10 minutes. Therefore connection will be
closed only it is not used for at least 10 minutes, not 30 seconds. Are you
sure that delay is caused by reopening a closed connection? If yes, are you
sure it's caused by idle timeout?

Answering your questions:
1. Generally it's OK, but I recommend you to investigate more first. What
you tell doesn't sound right.
2. The only drawback is that you spend resources on a connection that is not
used. In most cases this is not an issue.
3. If one of the parties shuts down, connection is closed anyway.
4. On all nodes.
