[求助] VASP计算中遇到的SIGSEGV, segmentation fault occurred错误

鄙人VASP计算入门，用VASP作HSE06计算的时候，老是算着算着出错了，POSCAR 文件空了（对一个字符都没有了），错误提示：forrtl: severe (174): SIGSEGV, segmentation fault occurred 不懂什么意思，重新算也偶尔这样，然而与它一块计算的任务却可以计算完。
这是错误文件：
forrtl: severe (174): SIGSEGV, segmentation fault occurred

  .o 的文件里面
For optimal performance we recommend to set                         |
|       NCORE= 4 - approx SQRT( number of cores)                            |
|    NCORE specifies how many cores store one orbital (NPAR=cpu/NCORE).    |
|    This setting can  greatly improve the performance of VASP for DFT.    |
|    The default, NPAR=number of cores might be grossly inefficient       |
|    on modern multi-core architectures or massively parallel machines.    |
|    Do your own testing !!!!                                              |
|    Unfortunately you need to use the default for GW and RPA calculations. |
|    (for HF NCORE is supported but not extensively tested yet)

求解答！感谢
