I am playing a bit with JMeter to produce some load on my Node.js system
(HTTP requests). I recognized, that under heavy load my master node process
in the cluster is using 100% CPU and will never stop doing so even if no
requests are arriving.I attached a screenshot... This was the situation
some minutes after the load. The whole system was relaxed again expect the
master in the cluster.
My cluster is build like the example
here http://nodejs.org/api/cluster.html#cluster_cluster So there is nothing
than master.fork() in master's code.
Any ideas what makes the master process busy? The application still respond
very fast in the 100% CPU master situation.
