WorkerPool Errors

Configuration

Hi.
I have errors related to WorkerPool:

16-04-10 09:41:32 homeassistant.core: WorkerPool:All 24 threads are busy and 145 jobs pending 16-04-10 09:41:32 homeassistant.core: WorkerPool:Current job from 09:23:23 10-04-2016: (<function setup.<locals>.start_digizigbee at 0xb44cf4f$ 16-04-10 09:41:32 homeassistant.core: WorkerPool:Current job from 09:39:01 10-04-2016: (<function _handle_get_api_stream.<locals>.forward_even$ 16-04-10 09:41:32 homeassistant.core: WorkerPool:Current job from 09:39:31 10-04-2016: (<function _handle_get_api_stream.<locals>.forward_even$ 16-04-10 09:41:32 homeassistant.core: WorkerPool:Current job from 09:39:31 10-04-2016: (<function _handle_get_api_stream.<locals>.forward_even$ 16-04-10 09:41:32 homeassistant.core: WorkerPool:Current job from 09:39:32 10-04-2016: (<function _handle_get_api_stream.<locals>.forward_even$ 16-04-10 09:41:32 homeassistant.core: WorkerPool:Current job from 09:39:33 10-04-2016: (<function _handle_get_api_stream.<locals>.forward_even$ 16-04-10 09:41:32 homeassistant.core: WorkerPool:Current job from 09:40:01 10-04-2016: (<function _handle_get_api_stream.<locals>.forward_even$

What does it means ?
How fix it?

I am using Digi ZigBee modules, with library created by me.
I am using CallBack function to update sensors status.

It looks like something is not returning control back to the worker pool after being called from a callback. Since you are running custom stuff I suspect that to be the cause.

Same issue with AIO installer.

I have not resolve this issue now, but i think this errors related to Operation System (installed pacages). It is occur only in Raspberry PI with LITE version of Raspbian. On Intel NUC all works good.
