SEGMENTATION FAULT during Molecular Dynamics

[Akanksha]

Hello CP2K community,

I am trying to run a molecular dynamics calculation on CP2K (version: 2024.2). My reaction system has one trans-stilbene and one 2-bromophenol in an explicit DMF (89 molecules) environment in a 30*20*20 box.
I receive the following error when I try to run this calculation using cp2k.ssmp or cp2k.psmp -np 4:

*********************

I have been struggling to figure out where the problem is and how I can fix it. I have tried increasing the available memory and cores, but it didn't help.

Could anyone please help me work this problem out? I would really appreciate your time and help.

Thanks a lot,

Akanksha
