[gmx-users] grompp not possible with annealing - Gromacs 2019.1

Dear all,

I try to use simulation annealing, but unfortunately the grompp - command leads to an error.
It is not a known Gromacs error, but it doesn't finish the job and it says: Speicherzugriffsfehler (Speicherabzug geschrieben) (which means something like "Memory Access Error")

The only output file produced is the mdout.mdp, which content seems correct.

The screen text is given below as well as the grompp.mdp content and the details to the system used.

There have been some issues as well to get Gromacs installed on the workstation. Not sure if this could be connected.
Many thanks already for your help.

Greetings,
Steffi

  You are using constraints on all bonds, whereas the forcefield has been
  parametrized only with constraints involving hydrogen atoms. We suggest
  using constraints = h-bonds instead, this will also improve performance.
