This is more a report for to a problem I encountered when installing GLUU Server 4.2 on an Ubuntu 20.04. The openDJ goes to 200% CPU usage, which makes the GLUU Server unresponsive. After some research (googling) I found a fix for it. GLUU server is using Java 11 in combination with an openDJ, which I haven't figured out yet. When you disable the TLSv13 on the Java11 security settings, the situation went back to normal. https://github.com/OpenIdentityPlatform/OpenDJ/issues/78 Can you please check if it already happened in your lab? Maybe an upgrade of openDJ would not let the CPU usage go through the roof. Thanks, David Tillemans

Interesting. I have noticed this also once on my Ubuntu 18 installation too.
