Setting the bug to HIGH because it is hit in BAT (which warrants HIGHEST), but the GUC is disabled by default (which warrants MEDIUM).
Possibly due to an intermittent Gen9 guc reload issue that can requires retry workaround and that will be tested. Otherwise, further investigation will be deferred until after upcoming update to guc version.
