RHEL 5.9
Jenkins LTS 1.509.1
My Jenkins is on the LTS release. I just upgraded it from 1.480.3 to 1.509.1. Now none of my SSH slaves work. They fail to start and the log contains the following:
[05/03/13 09:11:05] [SSH] Opening SSH connection to ###.local:22.
ERROR: Unexpected error in launching a slave. This is probably a bug in Jenkins.
