From your case.scfm file I can see:

zhang714@perlmutter:login21:/pscratch/sd/z/zhang714/wien2k_jobs/SrVO3> more SrVO3.scfm
:CINT001 Core Integral Atom   1    9.99999991
:CINT002 Core Integral Atom   2   27.99986575
:CINT003 Core Integral Atom   3    1.99999995
------------------------------------------------
So the core charges for V, Sr and O look perfectly ok. There is NO core leakage.

       CHARGES OF NEW CHARGE DENSITY
:NTO   : INTERSTITIAL CHARGE  =     0.000005
:NPC   : INTERSTITIAL CHARGE  =     0.000069
:NTO001: CHARGE SPHERE   1    =    19.285753
:NTO002: CHARGE SPHERE   2    =    35.475474
:NTO003: CHARGE SPHERE   3    =     7.894361

:NEC01: NUCLEAR AND ELECTRONIC CHARGE     85.00000    78.44432
:WAR : NEC01: average large charge leakage: 1.3111368889508412 e/atom :ERROR : NEC01: average charge leakage too large: 1.3111368889508412 e/atom
------------------------------------------------
Again, the charges inside spheres (:NTO001-3) look ok. However,
:NTO (charge in interstital) is definitely wrong. It must be much higher and accounts for the missing electrons.

First of all, check in your case.clmval file the Fourier coefficients of the density. (bottom of the file). Is the number of PW ok ? does the list of K vectors look ok ? Are the coefficients reasonable (or are they all nearly zero ?). Compare this list with the list in case.clmsum (coming from dstart).

Possible reasons for the problems:

case.struct (wrong symmetry operations). The case.struct you sent previously is ok, are you really using this one ?

lapw2: It uses FFTW for the Fourier part. Maybe recompile/reinstall (make all in SRC_lapw2; cp lapw2 lapw2c ..; check carefully for any error message. (If FFTW is the problem, also dstart and lapw0 should give a problem ?)

mixer: Also here, try to recompile.

Try other examples, eg. the simple TiC from the usersguide. Does it work ?
