[Pw_forum] a small problem

[贺伟]

Dear all:

     Happy new year!

     Now I have a small problem.When I run pw.x to make a relax calculation,in the
fourth step of geometry relaxation, there is an error message :

     linmin: 3rd order interpolation

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     from linmin : error #         2
     unexpected error
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     stopping ...
	
Would somebody tell me  the possible  reason for this error? Thanks!
