[gmx-users] Floating point exception in xtc file

[Marc Baaden]

Hi,

I just encountered an error I haven't seen reported on the mailing
list (lest I did a stupid error in my search). When running gmxcheck
on the xtc file, it complains

Checking file md_prod3.xtc
Reading frame       0 time 5000.000
# Atoms  69953
Precision 0.001 (nm)
Reading frame    2110 time 7110.000   Floating point exception

apart from that, the simulation seems to have gone well and to have
finished.

Anybody had a similar error ? A suggestion to "fix" the xtc file ?

 From past - unrelated - messages I would guess, maybe an NFS problem
during write, that was not bad enough to crash the simulation ? Any
other ideas ?

Should I throw it away or keep it ? (the dynamics was 7500 long, so I'd
feel comfortable continuing with the final gro  file).

Thanks in advance,
  Marc
