Summary: [3.11] Random outages with egressIP
Product: OpenShift Container Platform Reporter: Dan Winship <danw>

Priority: high    
Version: 3.11.0CC: aos-bugs, jack.ottofaro, joboyer, openshift-bugs-escalate, sburke, shiywang, travi, zzhao

Target Release: 3.11.z   
Hardware: x86_64

Whiteboard:
Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: If a pod using an egress IP tries to contact an external host that is not responding, the egress IP monitoring code may mistakenly interpret that as meaning that the node hosting the egress IP is not responding. Consequence: High-availability egress IPs might get switched from one node to another spuriously. Fix: The monitoring code now distinguishes the case of "egress node not responding" from "final destination not responding" Result: High-availability egress IPs will not be switched between nodes unnecessarily.

Ravi Trivedi yeah, if they can provide the details commands, that's more better. since I cannot reproduce this issue on 3.11.117 using the above steps. thanks.

Comment 17 Dan Winship 2019-07-08 13:47:07 UTC
This fix wasn't in 3.11.117; it was committed just after that version was tagged. So it didn't make the latest errata. I'm not sure how it ended up being listed as fixed there. (It will be in the next errata.)
