Yes, probably. I have faced the same issue. Have not tried SESDELAYED. May work. Try it.
I have been using:
create table schema.tablename
(fastload=yes sessions=4 tenacity=1 sleep=6 dbcommit=100000) as
But again it always does not work.
I would put a ticket in with SAS if you haven't done so already, they may have additional advice.
Please post their response. I am curious as well.
