Hello, I am trying to equilibrate a ionic liquid system (EMI-BF4) in Gromacs 4.0.5 version. If I reduce the box size to get expt. density, I get the error immidiately after the mdrun starts p0_22967: p4_error: interrupt SIGSEGV: 11
If I increase the box size the simulation goes ok. But the density gets lower. Is the problem in mdp file?
