[JENKINS-74952] If ssh/jnlp connection dies remoting calls are stuck in an infinite loop. #1504
Description
Seeing this happen with us frequently. I realize that we've got an underlying issue to fix with the ssh/jnlp connection just dying for no reason... but we keep having these process stuck on Request.java:177 indefinitely till a bounce is done of jenkins. Any way we could put a timeout or check to see if the channel is actually running?
