nova-api hangs havana ubuntu 13.10
Hi All,
I've built an openstack deployment using ubuntu 13.10 and havana. I have everything working.
randomly after a certain time of inactivity, nova-api stops responding.
The service is still up, and the process is still active, but the logs are empty and any attempt using the nova client timeout.
A simple restart of the service fixes it, but eventually it happens again.
I've enabled debugging but when it stops responding no log entries are written. All the other nova services still appear to work while this is going.
The nova-api freeze is certainly worrying! I would suggest to debug it referring [this](https://wiki.python.org/moin/DebuggingWithGdb) to get a better picture of what going on!
Ill give that a go after the weekend, but so far I think Im onto something. It seems like it might have something to do with creating an instance using the vmware vcdriver on a newly created image. The image needs to be uploaded to the datastore and when doing two creations at a time, it seems to hang. The process though is still going and all other services respond, and the vmdk file is growing despite the hung nova-api.
