[Pw_forum] Problem relaxing cluster

[Lucas Fernandez Seivane]

Hi to all

I am trying to relax a system of 2 atoms, but each time I do it I get
 IOS = 39

2
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     from davcio : error #        10
     i/o error in davcio

the input is

May somebody have this happened to before? I use ifort9 + mkl 8.0.1 on x86_64
thanks to all

P.S.: I know that the ecuts may be a bit low, but I wanted to check if
it was some kind of problem related to these parameters
