Hi, Here's a one-off regression test failure of a sort that commit 624e440a intended to fix. a_star unexpectedly sorted higher. I checked the space weather forecast for this morning but no sign of solar flares. More seriously, it did the same in all 3 Parallel Append queries. Recent commits look irrelevant. Could a UDP stats packet dropped on the floor cause that? Otherwise maybe you'd need a weird result from FileSize() to explain it. Based on log output no other tests ran around the same time.
