Sir/mam
I struck to the segmentation error, while doing the calculation on inclusion the spin- orbit coupling parameter ( LSORBIT = TRUE ) or non-collinear parameter ( LNONCOLLINEAR= .TRUE. ). Although, we have successfully installed the full version of vasp without any error.

It would be really appreciating if you can give some way out.

Yours Sincerely,

Very likely is this memory problem. Noncollinear case needs much more memory than a simple case.
Use smaller cell or more cores.

Hi
I posted the same problem this year. I tried to run the example from the tutorial, the small one (Fe slab) with the same problem SIGSEV.
I am still unable to run spin-orbit.
Best regards
Ricardo

This error was also observed when a different version of a compiler was loaded than that used to compile the code.
Suggested was to rebuild everything (including vasp.5.lib) and make sure that everything was consistent
(check your makefiles and do not use your makefiles from a earlier version).

Dear Sir,

Good day sir!

We just bought a VASP. We have an own workstation (DELL, Model: OPTIPLEX7080). 

We have successfully installed VASP 5.2 version with ifort. While we run to work, we get the following information:

We did not have any problems while working with VASP 4.6 version. If any, could you help me?

The "Unknowns" indicate that corresponding routines are missing.
That means your installation of vasp is not clean.

Hello:
I faced this error before, and I found a solution, just type "ulimit -s unlimited" in your terminal. Actually, this is an error about stack size. I found this solution in this page:

Hope it helpful!

I have the same problem and this really solves the problem! actually, you can add this line in ~/.bashrc so every time you have a new terminal this line will be run.
