This is not a new issue, we see this every few months. In the past I think
this was solved by restarting gerrit.
I compared our gerrit to other installations:
https://go-review.googlesource.com/
https://review.opendev.org/
Both reloads in about 1 second. Our gerrit takes 10-15 seconds.
Go gerrit is using:
3.3.1-812-g388176bbb4
Openstack is using:
3.2.6-28-g4a9ffec296-dirty
We use:
2.16.23
Looking in
https://www.gerritcodereview.com/ current version is 3.3.1.
Looks like we are using an old version.
