[Wien] LAPW1 crashed!

[Mahmoud Payami]

It was updating problem as Peter Blaha had pointed out before:
--------------------------
> Check with   lse    the dates and sizes of all *lapw1*.error files.
> If lapw1_1/2/3/....error are empty, but lapw1.error has these "unspecific"
> errors in it, this may indicate a NFS problem (file update is delayed).

> You may increase  "sleepy" in lapw1para,
> add the "async" parameter in /etc/exports  and
> "actimeo=2" in /etc/fstab (for the NFS mounted directory.
-------------------------

I changed the "sleepy" in lapw1_para from 1 to 2 and it seemed after one
cycle the system really slept.
I ran once again without changing any parameter it converged after 40
iterations.
Thanks to Peter Blaha's comment.
