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,
