Could you file a bugzilla?
And what do you mean with "-dlb on"?
on is not an option, the options are: auto, yes, no

Subject: [gmx-users] Getting some interesting errors.
Running several free energy perturbation (FEP) runs to further understand how I should set up my larger production runs and I keep getting errors that I cannot find in the gmx-user email or anywhere specifically online.
I get this error on three of my four runs.The system is a single rna in a water box. Amber03 and tip3p. Two are cyt an the other two are gua. I get through energy minimization (steep) and I fail on positional restriction sd. I can continue on if I turn -dlb on but I get error 2 below.
Some interactions seem to be assigned multiple times...
This seemed to occur after a restart of a failed job due to loss of HDD available space. I am trying to reproduce this error.
This error only comes up if I turn "-dlb on" in the above step. I get through energy minimisation (steep), positional restraint (sd) and I then fail on step 0 of my production run (sd).

Both jobs are running on a linux cluster running SGE. I have had several jobs finish on this cluster with no problems. I am also running a slightly modified 4.5.1 version. The topsort.c file in the source code was missing a line of code and I was getting Improper Dihedral in ip_pert errors. I have run several methane hydration FEP's with very similar results. I am hoping this is a small problem that can be fixed easily.
Thank you for any assistance,
