[modeller_usage] Error: Ran out of slaves to run tasks

[Xiao-Ping Zhang <>]

Dear Modellers,

When I was refining loops for a model in parallel, I asked modeller to
generate 9999 models. But modeller stopped at 1245 with the following
error. The computer has six cores, modeller uses four of them. The other
two cores were free. 

Thank you for your help.
