[QUOTE=chris2be8;559576]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[/QUOTE]

Done.

I'll do the LA.

NB. Does it matter if 15e_small runs dry? It's been a while since anyone else submitted any jobs to it.

Chris[/QUOTE]

It won't. I have a few jobs lined up, for one- but the queue has been pretty long the last couple weeks, so I haven't submitted. If it does get close to dry, we'll just post one of the smaller regular-15e job to it.
