All, I am intermittently seeing a job fail with: ERROR: Too many updates/deletes within transaction. Reader gang not able to provide correct visibility (combocid.c:270) (seg1 slice1 sdw1:50002 pid=15588) SQL state: XX000 Does anyone have any ideas what this really means? So far, waiting until system usage is low and rerunning seems to let it go through, which would suggest to me this is a miss leading error at best. The "transaction" doesn't really seem to be the problem. This is happening on as CREATE AS SELECT.
