Hello Experts

I am getting issue while launching instance in Packstack-Queens.

I am using RHEL7.6 server (All in one installation)

I went through the keystone and nova-api logs and found below warnings

nova-api.log

2019-02-26 14:36:42.526 29927 WARNING keystonemiddleware.auth_token [-] Using the in-process token cache is deprecated as of the 4.2.0 release and may be removed in the 5.0.0 release or the 'O' development cycle. The in-process cache causes inconsistent results and high memory usage. When the feature is removed the auth_token middleware will not cache tokens by default which may result in performance issues. It is recommended to use memcache for the auth_token token cache by setting the memcached_servers options.

keystone.log

2019-02-26 14:32:26.489 29676 WARNING oslo_config.cfg [-] Option "driver" from group "token" is deprecated for removal.Its value may be silently ignored in the future.

Does anybody facing such issue? please share you experiences.

These are only warnings that certain configuration settings will not be available in future releases. They have nothing to do with your instance launch. Look for errors in the Nova log files, then possibly Neutron logs as well depending on the Nova messages.

I found error in Nova-api.log . It has something to do with Database connection loss . The process retry it number of times to connect. Any solution for such case??

pls find error file URL : https://drive.google.com/open?id=12BrGXgMFCrWi9R3CjbLYXKlrj9K7lY5O (https://drive.google.com/open?id=12Br...)

check if you can manually connect from compute node to the DB using the credentials from your nova.conf.
