October 31, 2017 : Single-node restart

A single Blackboard node (bbprd7) was logging a large number of Nagios memory alerts. Tomcat was using an unusually large amount of memory on that node. Tomcat was restarted to clear the problem. This did not affect end users, as the traffic was automatically routed to other available nodes. After Tomcat restart, memory utilization on bbprd7 stabilized to normal levels.
