error message while running job parallely

LYZ

Dear friends,

I have a 3d problem with 80,000 meshes generated. It has no problem to run under one PC or several PCs running interactively. However, as long as I ran the job parallely on background. I always got the error message as following:

> Halting due to end of file on input. node 0 retrying on zero socket read..... node 0 retrying on zero socket read.....

I tried to regenerate the grid but the same error occured. Do you know what's the problem?

Thanks,
