Description of problem:
openshift-router process is not updating the ha-proxy files and seems to be stalled in some part of the loop.

Logs and files have not been updated for weeks (since May 31st)

oc get routes works within the pod. There are two pods and the other one is working properly.

It is not even doing the full refresh every 10 minutes.

Version-Release number of selected component (if applicable):
registry.access.redhat.com/openshift3/ose-haproxy-router         v3.5.5.5

How reproducible:
Only seen once

Steps to Reproduce:
1. Create a route

Actual results:
Configuration files and logs are only updated on one of the pods

Expected results:
Both pods should be udpated with the latest configuration.

The culprit was probably https://bugzilla.redhat.com/show_bug.cgi?id=1415112 (fixed in I believe).

Comment 5 Ben Bennett 2017-06-21 10:04:55 EDT
It is either https://bugzilla.redhat.com/show_bug.cgi?id=1415112 or https://bugzilla.redhat.com/show_bug.cgi?id=1429823 (fixed in

Both identified problems with the EventQueue that we were using and both can lead to router lock-ups.  The symptoms of a router that stops updating the config file better match the notes in https://bugzilla.redhat.com/show_bug.cgi?id=1429823 but in our investigation we found that https://bugzilla.redhat.com/show_bug.cgi?id=1415112 can lead to the same symptom.  It is easier to make the event queue lock up by changing the labels, but rapid route insertions and deletions were later found to expose the same bug.
