…dered (#1937) Signed-off-by: Neetha John <nejo@microsoft.com> Fixes sonic-net/sonic-buildimage#9292 What I did Pfcwd was not getting started after executing load_minigraph after the changes done in #1508. This was because the PORT_QOS_MAP table is not yet present in config db (this gets populated only after the buffer templates are rendered) at the time we try to start pfcwd and hence the 'pfc_enable' field will always be empty and we skip writing PFC_WD table entries to config db. How I did it Delay pfcwd start until the buffer templates are rendered How to verify it Issue "config load_minigraph" with the changes and ensure that pfcwd is started on all active ports

But don't see it started
