Sam Talebbeik commented on JENKINS-11622:
-----------------------------------------
One more piece of information. This issue happened again the other day while
the target build slave server was cloning a repository. This means that the
build slave server was very busy doing I/O and cpu activities.
Could it be that the pinger's timeout is too short and too aggressive for
situations like this? If the network is very busy and if the target build slave
server is too busy with I/O and CPU activities then the response will not
travel fast enough from the main Jenkins server to the build slave server and
back from build slave server to the main Jenkins server.

> Key: JENKINS-11622
> URL: https://issues.jenkins-ci.org/browse/JENKINS-11622
> Project: Jenkins
> Issue Type: Bug
> Components: core
> Environment: Windows Server 2003, 1 vCPU, 4GB RAM (32bit) 8GB RAM
> (64bit), 50GB virtual disk, VMware Hypervisor.
> Reporter: Ryan Hass
> Labels: channelpinger
>
> Windows slaves randomly disconnect while idle. This appears to be caused by
> free space threads which are stuck or still running, resulting in the SSH
> conenction being terminated and connections being reestablished.
> I am not exactly sure what the expected behavior is for the low-level
> handling and communication. However, at a high level, the expected behavior
> is for the slave connections to persist the channel pinger not to cause a
> reset.
