Description

Ambari Web UI threads blocked when Server CPUs > 64, So the web ui will not response any thing till the browser timeout. In ambari-server.log it will logging a "Insufficient Threads configuration" It's should be a Jetty container bug.

So I change the ambari-server/src/main/org/apache/ambari/server/controller/AmbariServer.java

serverForAgent.setThreadPool(new QueuedThreadPool(25));
server.setThreadPool(new QueuedThreadPool(25));

to

serverForAgent.setThreadPool(new QueuedThreadPool(65));
server.setThreadPool(new QueuedThreadPool(65));
