> version:  PWSCF v.5.2.0
> The errors I get are below and output and input attached. I have
> greatly increased cell_factor to 3.0 and  ecutrho up to 1000, and this
> reduces the number of failures to about 20%, but still seems it
> shouldn't happen. I understand the cell changes a lot during the
> optimization. That is normal because I am doing crystal structure
> searching. It is automatic, so just rerunning by hand is not an
> option. Thank you for any help!
