Dear SIESTA user,
I already sent this email but I did not receive any answer, hopefully this
time.
I have a problem with relaxing a slab containing 447 atoms, I run it using
64 processors but it always stops after first "CG move" without any error.
the last lines in the OUTPUT file are these:
------------------------------------------------------------

in stderr file I can see this error :
------------------------------------------------------------
----------------------------------------------
NOTE: orbital pair 4609 4488 (at least) is multiply connected.
NOTE: Harmless for Gamma calculations, except if a COHP analysis is
intended.

mpiexec noticed that process rank 60 with PID 482517 on node compute-5-12
exited on signal 11 (Segmentation fault).
------------------------------------------------------------

I am wondering if any body could help me to solve this problem.
The fdf file is also is like this:
