Let's say, with 3 nodes, submit 450 callables to a ExecutorService with default config. These callables have 30 sec sleep, so after they are submitted and future.get is called, there is excessive logging of:

In some cases, it causes hundred MB of logs to be created. This logging noise can be reduced to debug level since it basically saying "everything is alright".

@sertugkaya: this mechanism is completely changed in 3.7. Are we going to have any other 3.6.x release?
