I compile vasp on our IBM p575 server using makefile.rs6000(using OS :AIX 3.5 ML6) , but when
i am running the task(INCAR file option "IBRION = 6"), i get a core file.

attached file.( vasp version 5.2.12(64bit)) input.zip => job submit file , output.zip => job output file.

Operational test of the INCAR file when IBRION 1 and 6,
total_tasks 32 (core) and four kinds of 64 when tested.

("ib1" folder : IBRION=1 32core, "64ib1" folder : IBRION=1 64core, "ib6" folder : IBRION=6 32core, "64ib6" folder : IBRION=6 64core)

ib6 folder "segment fault" error message.(INCAR file IBRION 6)
64ib6 folder "OUTCAR" at the bottom of the file,(INCAR file IBRION 6, 64core)
Error EDDDAV: Call to ZHEGV failed. Returncode = 197 2 128
Confirmation message, and will be judged abnormal.

we have never been reported such an error (using IBRION=6) before, I suppose it is not vasp-related.
please check whether your INPUT geometry is reasonable, this may lead to the ZHEGV error

Our POSCAR is like this, and it worked when we tried it on the other machine, but if it has a error, could you let me know?
