A fault reported when I try to using barostatting methods in a parrallel job

Hello Everyone,

Before I ask my question, I would like you to thank everyone who has
tried to develop LAMMPS. This software is awesome! I am a newbie in
LAMMPS.
    I write a script for thermostating and barostating a system, it works well in a serial run on my PC. But when submit it to the server of our insititute, it doesn't work. If I comment out the command "fix 2 all npt temp 300.0 300.0 0.2 aniso 0.0 0.0 0.2", and use a "fix
nvt" fix, it works again. I have also tried "fix 3 all press/berendsen aniso 0.0 0.0 0.2",
and met the same fault as "fix npt":

        How can I fix this problem?

   How can I fix this problem?

there is too little information in your post to give an answer.
segmentation faults are almost always a secondary symptom,
i.e. the real error is something else. please provide more details
and ideally post a (simple!) input that reproduces your problem,
so that people can easily try it out and make comments.
