[JIRA] [remoting] (JENKINS-22722) Master doesn't show connected slave

[o.v.nenas...@gmail.com (JIRA)]

Title: Message Title

Oleg Nenashev commented on JENKINS-22722   Re: Master doesn't show connected slave So there at least one scenario, which leads to the issue. 1) On the slave side we have just a SocketRead timeout, which commonly means that it didn't receive any command from master. Commonly Ping threads on master and monitoring jobs should reset this timeout. 2) When such issue happens, it terminates the SynchronousCommandTransport$ReaderThread on the slave side. When it dies, the slave stops answering to any command coming from the Jenkins master. And it causes the connection timeout on the master side. 3) Slave is being reconnected successfully 4) But then the Connection timeout happens on the master side. We recently had a conversation with James Nord about this issue. The decision is that SocketTimeoutException should not lead to the full termination of the receiver thread on the slave side. So the SynchronousCommandTransport$ReaderThread should be patched.
