Comment 2 Jeff Cantrill 2020-05-27 15:42:47 UTC 
Dropping to severity:low as this does not block 4.5
Comment 3 Jeff Cantrill 2020-06-03 15:57:17 UTC 
This may need a 4.5.z backport
Comment 4 Periklis Tsirakidis 2020-07-10 14:26:55 UTC 
Moving to UpcomingSprint as unlikely to be resolved by EOS
Comment 5 Jeff Cantrill 2020-07-31 17:56:30 UTC 
@peri re-assigning to you since they are likely the same fix
Comment 6 Jeff Cantrill 2020-08-21 14:11:19 UTC 
Moving to UpcomingSprint for future evaluation
Comment 7 Jeff Cantrill 2020-09-12 01:58:24 UTC 
Moving to UpcomingSprint as unlikely to be addressed by EOD

Marking UpcomingSprint as will not be merged or addressed by EOD

Closing NEXTRELEASE as its resolved in 4.6.  There are no customer cases attached and the one target customer is moving to 4.6 shortly
