[jira] [Commented] (BEAM-3407) Frequent Jenkins failures due to
"Backing channel 'beamN' is disconnected"
[ https://issues.apache.org/jira/browse/BEAM-3407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16443034#comment-16443034 ]
Scott Wegner commented on BEAM-3407:
------------------------------------
The jenkins machines have gotten really unreliable over the last few days, with this error message. Is there anything we can do in the short-term to get the machines back to a healthy state? This is impacting our ability to validate the Gradle migration /cc [~jasonkuster]
