link to same quantum bug (closed) https://bugzilla.redhat.com/show_bug.cgi?id=962385#c9 Since this only occurs when an incorrect user/password is used, it implies that the issue only occurs before you've got a functional cloud infrastructure (can't have a working cloud w/o having qpid connectivity, etc) So, I think this is worth release noting and fixing in the next release. (In reply to Perry Myers from comment #2) > Since this only occurs when an incorrect user/password is used Reconnect situation can happen any time there's an issue with connection during operation e.g. temporary network outage. https://github.com/openstack/nova/blob/2013.1.2/nova/openstack/common/rpc/impl_qpid.py#L372 Fixed in Nova havana-1 https://github.com/openstack/nova/commit/b4826d85c25a56ad95ffb76c467cdb459daba0c4 Will be included in stable/grizzly 2013.1.3 release. Steps to reproduce: ------------------- 1)Change in qpidd.conf -> auth=yes 2)Restart qpidd '/etc/init.d/qpidd restart' 3)Create qpidd user and password by running (Enter: guest/guest) : 'saslpasswd2 -f /var/lib/qpidd/qpidd.sasldb -u QPID guest' 4)Check the created qpidd user/password by running : 'sasldblistusers2 -f /var/lib/qpidd/qpidd.sasldb' 5)Attempt to boot instance ( should work!! ) 6)Change ion nova.conf : qpid_password=guest --> qpid_password=badguest 7)Attempt to boot instance. ( should stuck!! ) 8)While the boot command stuck, check the number of opened sessions by running: "watch -d 'netstat -n |grep 5672 | wc -l' " The number of open sessions should not constantly increase, but the number should reduce as well, when there are connections that are being closed. Note: ------- When the bug reproduces - 'netstat -n |grep 5672' will show increase number of open sessions, that are being stopped only when stopping the nova command (ie - "boot"). Some sessions will only be closed when password is being restored. More info: ----------- https://docspace.corp.redhat.com/docs/DOC-148763 This issue is not reproducible when stopping cinder service - the number of connections reduces and it work as it should. According that info - this nova bug will be closed and copied to cinder Bz#1000972. Verified - with openstack-nova-2013.1.3-2.
