 2020-10-11, 15:56 #22 chris2be8     Sep 2009 7FA16 Posts f57_142p1 is on the wrong queue. Hello, Sorry for the abiguity in my post, I meant sieve f57_142p1 with the 15e siever, but on the 15e_small queue. Can you move it from the 15e queue to 15e_small (it's not started sieving yet so could be killed and a new job started). Chris
