Not writing md.log file for long simulation

User discussions
1

Recently, we updated the ubuntu server version and reinstalled the gromacs-2023. The small run simulations finished successfully. The longer simulations100 ns or >100ns are having issue to finish successfully. The top command shows that the gmx is running, but its not writing the md.log or .trr or edr files. The output file is not updated after around 65 ns for recently 100ns simulations.

I am having same issue with gromacs-2023 also. We have installed Ubuntu 22.04.5 server.
this run are commpleted with last installation of gromacs and ubuntu.

Is this a installation issue ? How to resolve this issue ?

Thanks,
Maryam Abbasi

There is an identical issue here: Not writing to output file for long simulation

Since multiple people reported this, I am starting to think there is some operating system issue with long running processes hanging.
