The issue is around Tomcat clustering. A 4 server cluster, 2 servers were rebooted last night and now the 2 that didn’t reboot are unable to communicate with the other 2 or with each other. Even after restarting those 2 servers.
All 4 servers have 10.1.47. Cache may not have been cleared on any of these.
