Verified in "4.5.0-0.nightly-2020-10-22-024721" release version. The periodic reaper error does not occur with the patch in place.

@steve greene

I have another customer seeing the error "931:E1103 15:36:29.512244       1 limiter.go:165] error reloading router: wait: no child processes" intermittently in router pod logs. They could not see any functional impact but are checking with app teams and end-users.

Is seeing that error a confirmation that the race condition exists as captured in this BZ ? or would you recommend any other tests?   The customer recently upgraded and does not want to upgrade again without confirming that this BZ definitely applies to their issue.


Thanks
