Hi,

Hi All,

I had this problem running MD on a single Debian machine:

Program mdrun_d, VERSION 3.3.1
Source code file: stat.c, line: 257

Fatal error:
XTC error


There is no chance of being size exceeded of file or quota, or disk error.
I compiled gromacs with gcc-3.4...

Does anyone know what this error means? Gcc version may be the cause?

Thanks,

Luciano P Gomes



it can also mean that your system is exploding.

No.
The xtc file doesn't opened. It crashed VMD.

I forgot saying that I was running simulated annealing protocol with a DNA 
molecule and crystallographic water molecules (HOH) freezed, only moving ions 
and water molecules placed by genbox (tip3p). The crash occured on 2 ps of 
simulation time in a temperature of 50K. I had excluded non-bonded 
interactions: DNA DNA HOH DNA HOH HOH.

I am running now a simple MD at 300K and this error haven't occured yet.
I am trying to understand...

did you use pressure coupling? you can not have Pcoupl with freezing and constraints.


Thanks,
Luciano
