[Pw_forum] from electrons : error # 1 charge is wrong

[Neel Singh]

Hi,

 i am trying to relax a structure but after two iteration i am getting this error, Please help or advice, My input file is listed below.
Thanks in advance

 iteration #  1     ecut=    40.00 Ry     beta=0.20
     Davidson diagonalization with overlap
     ethr =  1.00E-02,  avg # of iterations =  1.0

     total cpu time spent up to now is    252.18 secs

     WARNING: integrated charge=   286.80000000, expected=   287.00000000

     total energy              = -2892.51662082 Ry
     Harris-Foulkes estimate   = -2894.39255945 Ry
     estimated scf accuracy    <     6.18305675 Ry

     iteration #  2     ecut=    40.00 Ry     beta=0.20
     Davidson diagonalization with overlap
     ethr =  2.15E-03,  avg # of iterations =  2.0
