Horizon dashboard stop responding with gateway timeout error
Last modified: 2017-08-04 05:01:47 EDT
Description of problem:
Seen in rhosp 10 horizon dashboard. After running few days, I am able to login as admin to horizon and view the identity tab. However clicking on the admin tab will timeout with error 504 gateway timeout error.
Version-Release number of selected component (if applicable):
Will upload sosreport from all three controllers to box and provide link
sosreport at box
I don't see any errors related to that in the horizon or apache logs on your controllers. That suggests that the error may be actually happening earlier, when the haproxy is trying to reach your controller nodes.
Can you verify that there are no network connectivity problems with the controller?
Also, when that happens, does only happen with that single view, or all of Horizon?
Can you also show us the logs of HAProxy?
There is no network connectivity issue. I am able to login to Horizon Identity dashboard everytime. From there, if I attempt to navigate to the admin or project tab thats when it start to timeout. If I attempt to login to Identity again it will succeed, but attempt to navigate to admin tab or project tab will timeout again.
btw, I dont see haproxy log in /var/log/. where can I grab it?
Hi, does this happen on rhos 7.4 by any chance? Because we have a similar problem with mod_wsgi there: https://bugzilla.redhat.com/show_bug.cgi?id=1478042
