[Wien] Parallel job error

Dear Wien users,

The calculation (with the input file below) runs to convergence with 1 k
point and 1 processor. It takes about 18 hours for 18 cycles.

Then with higher number of k points with multiple processor it always
fails.  It gets stuck after LAPW1 END in the first cycle. Following is the
part of dayfile-

[1]  - Done                      ( cd $PWD; $t $exe ${def}_$loop.def; rm
-f .lock_$lockfile[$p] ) >>  ...

Then it seems to be static and not moving forward.

This calculation involving NaNbO3 has never converged in a parallel mode
but   I could manage with other systems like TiO2 and NbO2. Regarding
static and floating as previously mentioned in board for compiler
options/flags, it seems this is not an issue in our case.

Is there any other parameter that has to be set after switching to
different  space groups or system with different number of atoms? I guess
this is not the cause. Why is this system different from NbO2 which runs
fine in a parallel mode? There is something with parallel option in the
present case that we are missing.

Any help regarding fixing of this error will be highly appreciated.

Have a happy lunar eclipse.
