On a non-ha juju controller, with just the default model, but managing machines with lots of network devices (openstack neutron) being created or deleted, upgrading to 2.8.3 ended up with a very slow controller, which errors when just trying to get a juju status on the default model:
ERROR could not fetch IP addresses and link layer devices: cannot get all link layer devices
https://pastebin.canonical.com/p/hXkDM32dTn/
The linklayerdevices collection:
From `db.linklayerdevices.find().explain("executionStats")`:
"totalDocsExamined" : 795837
is suspicious.
These are all the qvb*, tap*, qvo*, qbr* interfaces.
We started investigating with manadart (to whom I proveided a dump) and achilleasa. This bug is to capture further investigations. |
