It is a bit hard to guess what could go wrong, since you are not telling us how you parallelize (how your .machines file looks)

Since you say:
a) for smaller systems it works
b) sometimes it works

it could be a memory problem. Try to use less k-parallel processes and while it is running, check with eg. "top" how much memory is used/free in the lapw1 step.

have been trying to run SCF of ZnO with Mg. I have built ZnO supercell
and replace one Zn with Mg. after that, i have done initial calculation.
everything is fine and no error. when i go for SCF i am getting below error . I checked several times my inputs, everything looks like fine, without supercell is working perfectly. And sometime with same set up it is working also.
