Dear List members I am trying to use FIXRHO UPWFN 
for wave function optimization. I think that there is a typo in the manual
where it says :
FIXRHO UPDWF It should say: FIXRHO UPWFN

When trying to use this method I get the following error :

 ***  CALC_ALM| THE NEW SIZE OF THE PROGRAM IS  549460/1837104 kBYTES ***

 DEGREES OF FREEDOM FOR SYSTEM:                                36

p0_26498: (2234.738281) net_send: could not write to fd=4, errno = 32

This error is not present if I use PCG MINIMIZE (I tried different
timesteps)
but PCG MINIMIZE fails to converge.


Does anybody has any suggestion about how to solve this problem ?

Thanks in advance,

Eduardo
