I have the following problem:
First, the job scheduling didn't work.

I tried to upload a file, but the job was waiting.
Then I checked "squeue", which timed out.
The slurm service was running.

Then I restarted the cluster.
Now I even have problems access the cloudman admin page.
Meaning, the page is loading endless.
The machine is not busy (CPU and mem @ htop)
In the paster.log it tries this every 4 seconds:

2015-06-16 18:35:56,547 DEBUG         master:2579 Trying to setup AMQP connection; conn = '<cm.util.comm.CMMasterComm object at 0x7f0aa26d72d0>'

2015-06-16 18:35:56,548 DEBUG           comm:49   AMQP Connection Failure:  [Errno 111] Connection refused

Any idea what this might be?
Something seems to be really weird.

I am using the next version of CloudMan (dev).
I created an own instance with the Cloud Man playbook.
