[CP2K-user] [CP2K:22204] CP2K stops with “Problem moving file” during xTB-DFT-MD simulation

Hello,

I am running an ONIOM-like xTB-DFT-MD simulation in CP2K. After a fairly 
long run, sometimes even after around 4000 steps, the calculation stops 
with the following error:

"Trying to move RuWOC_ONIOM-RESTART.wfn.bak-1 to 
RuWOC_ONIOM-RESTART.wfn.bak-2.
rename returned status: -1

Problem moving file"

I tried setting BACKUP_COPIES 0, but that did not solve the issue.

Has anyone encountered this problem before, or does anyone know what might 
be causing it?

Regards,
Hasan
