cannot restart from restart file

Dear All,

Unfortunately it's happened recently quite often that my jobs are  
killed due to last minute-announced updates etc. I'm trying to restart  
it from the saved restart files, but I can't, because during the MD  
simulation some atoms move too close to one another, and CP2K aborts  
during the neighbour list building.

Here's a file I used to test if I could restart the calculation. I  
performed 5 steps and then I tried to run the restart files to see if  
I could get the same trajectory.
When I try to run any of the saved restart files, the program aborts  
immediately (see error message below). I checked the geometry, and the  
atoms are closer than the threshold. If I increase the EMAX_SPLINE,  
the temperature goes up to > 100 000 K and aborts with basically the  
same error message.
However, running the original input file (please find attached), I  
don't even get warning messages, although the atoms get closer than  
the threshold for the spline construction.
What's the difference in the 2 cases and why can't I obtain the same  
trajectory? I would expect to be able to. Am I wrong?
I would really appreciate if anyone could help me!

Thanks very much,

Csilla
