I opened bug 1341777 [1] against glance but it looks like it's due to
the default log level for requests.packages.urllib3.connectionpool in
oslo's log module.
The problem is this warning shows up nearly 420K times in 7 days in
Tempest runs:
WARNING urllib3.connectionpool [-] HttpConnectionPool is full,
discarding connection: 127.0.0.1
So either glance is doing something wrong, or that's logging too high of
a level (I think it should be debug in this case). I'm not really sure
how to scope this down though, or figure out what is so damn chatty in
glance-api that is causing this. It doesn't seem to be causing test
failures, but the rate at which this is logged in glance-api is surprising.
