Francesco Mari resolved OAK-4884.
---------------------------------
Resolution: Fixed
The latest five builds on the Jenkins instance I use don't show any failure
related to cold standby. Before this fix, some cold standby test was randomly
failing every two or three builds. I will resolve this issue for the moment,
but will keep an eye open for future random failures related to connection
problems.
