Description Alan Pevec 2013-10-01 09:28:55 UTC 
+++ This bug was initially created as a clone of Bug #1008818 +++

Description of problem:
Glance api can hang in registry notification.

Version-Release number of selected component (if applicable):
RDO havana

How reproducible:
Usually

Steps to Reproduce:
1. openstack-config --set /etc/glance/glance-api.conf DEFAULT workers 1 
2. service openstack-glance-api restart
3. Try several times:
for ((a=0; a<16; a++)) do
        glance  image-create --name image-$a --container-format bare --disk-format raw --file /etc/passwd &
done

Actual results:
glance image-list # Times out
API service hangs for forever.

glance-api service restart is required to continue the normal operation.

Expected results:
Service does noh hangs.


Additional info:
- On F19-devstack havana, RHEL-RDO-havana with pyhon-qpid 0.14 .. 0.24
- Tested on a 2 Core VM
- With rabbitMq the response is 500, so the bug can be related to the glance-registry. 

- No issue seen with workers=2 yet.
- glnace image-create command without the --file argument also can cause hanging issues.
