kafka-manager is blocked and it takes more time to start play.api.Play and listen on 9000
here is the logs:

It takes more than 15min to start play.api.Play, and listen on 9000. the jstack shows:

i have no idea how to fix it and everything that i did does not work, eventhough i use the newest cmak. i use kafka1.0.0 in my mechine.
Hm, how many cpus/threads does the machine have?
it is a standalone Kafka~ The machine has 1 cpus and 1 threads. I tried 2 cpus and 2 threads, and it take more than 5 min to listening for HTTP:9000 . Is it necessary to make sure more cpus? Kafka works well when only 1 cpus.
