We have just migrated our Jenkins master from a Centos 5 m/c to a Centos 7 m/c. The console log now shows some RemoteInvocationHandler statistics and an exception. Any thoughts why these are happening please?

Jenkins is fully up and running

Hi David,

I think the exception is due to https://issues.jenkins-ci.org/browse/JENKINS-50748 and is allegedly fixed in Jenkins 2.117 (https://jenkins.io/changelog/).
