Installed 2.5 on Ubuntu 12.04

Having problem with UI, when i try to add a show, or drag a song into a show, the browser freezes (firefox/chrome) and page greys. The action is completed. but i think rabbitmq never responds back and db corrupt.

2013-10-31 08:21:11,255 ERROR - [pypomessagehandler.py : main() : line 99] - Error connecting to RabbitMQ Server. Trying again in few seconds
repeats in log every 10 seconds.

Questions:
1) Not sure how to clear the rabbit db? and restart.

2) airtime-check is fine? Does'nt this check rabbitmq?

thanks for your help.

I was able to fix. delete the files in mnesia.
reboot rabbitmq.

then i issued the following shell commands to grant permissions

rabbitmqctl add_vhost /airtime
rabbitmqctl add_user airtime K7Q<this is key in airtime conf>ENB
rabbitmqctl set_permissions -p /airtime airtime "airtime-pypo|pypo-fetch|airtime-media-monitor|media-monitor" "airtime-pypo|pypo-fetch|airtime-media-monitor|media-monitor" "airtime-pypo|pypo-fetch|airtime-media-monitor|media-monitor"

Everything works fine now.

Hope this helps someone in future that doesnt set hostname first.

regards,
Stephen

Getting closer to solving.    I changed the hostname after install and see this messes with the database names in rabbitmw mnesia directory. I removed and restart server.

New db files are built. but

=ERROR REPORT==== 31-Oct-2013::09:00:05 ===
exception on TCP connection <0.665.0> from 127.0.0.1:41334
{channel0_error,starting,
                {amqp_error,access_refused,
                            "AMQPLAIN login refused: user 'airtime' - invalid credentials",
                            'connection.start_ok'}}

So how does the credentials work.    it must be tied to original hostname some how?

Stephen - thank you so much - after extensive mucking about, this was exactly my issue. Solved for me too.

I wish I had read this thread yesterday! Today I spent hours figuring it out for myself :(
I was changing hostnames on the fly so that I could have multiple airtimes behind a NAT.
It caused havoc with Rabbit. Now I use a fake hostname system I dreamed up - and that now works behind NAT.

thank you so much Dude! my initial install with Airtime and this was the last hurdle! Kudos.

Howdy, Stranger!
