In my CH + stable/newton setup, I brought up 5 heat stacks each having 100 nova instances in the same /16 network.
Deleting those heat stacks failed due to the below error.
"
2016-11-03 17:27:34.146 2399 ERROR nova.api.openstack.extensions TimeoutError: QueuePool limit of size 50 overflow 50 reached, connection timed out, timeout 30
"
Because of this error, out of 500 instances, deletion of about 67 instances got failed.
With default parameters in neutron.conf, I'm getting the below neutron error.

Please look into this. |
In my stable/newton setup running on a VMware NSX platform, I brought up 5 heat stacks each having 100 nova instances in the same /16 network.
Deleting those heat stacks failed due to the below error.
"
2016-11-03 17:27:34.146 2399 ERROR nova.api.openstack.extensions TimeoutError: QueuePool limit of size 50 overflow 50 reached, connection timed out, timeout 30
"
Because of this error, out of 500 instances, deletion of about 67 instances got failed.
With default parameters in neutron.conf, I'm getting the below neutron error.
