What does STOP_SINGULIER does?

When node numbers are huge and number of boundary nodes are small, code aster spits out "Singularity ERROR or near singular error" and saying some loss in precesion. But during analysis if i check off STOP_SINGULIER there is no error. Can anyone explain what is the cause of this error and why there is no error when i check off? What is nearly singular case?
