I’ve upgraded discourse using the UI, running on a docker image on Ubuntu 14.4. The entry page as well as the admin pages work, even the search is working. But all the topics are no longer accessible and it seems to load forever then at some point times out.

I’ve then rebuild the app via the docker commands, but it did not improve. Then I upgraded the machine itself via apt-get and rebuild the app again. But still it has the same symptoms.

What I find a bit strange that the version says: installed: `v1.6.0.beta1 +281` and latest: `1.6.0.beta2` and shows `You're up to date!` The update logs do not show something problematic to me.

Is that a failed upgrade? How would I know and re-trigger the upgrade, as the UI does not provide an upgrade button now that it thinks it is up-to-date

**Edit** Maybe related to this here: [Unable to upgrade even though running on older version](https://meta.discourse.org/t/unable-to-upgrade-even-though-running-on-older-version/42967) hmmh but I have 4GB of memory and 1 physical CPU core. @envieme as the topic is already closed: do you see the correct installed version now? And what are your RAM settings for the DB and how much RAM do you have available?

There seems to be some strange SELECT statements taking several dozen seconds and 5-10% CPU:

```
