[gmx-users] graph edges bug?

[James Rustad]

Hi List,
I am running into a "max graph edges exceeded" problem with
gromacs 3.3.
I can run my molecule fine with "pbc = no" but when
I change it to "pbc = xyz" I get
-------------------------------------------------------------
Program mdrun_d, VERSION 3.3
Source code file: mshift.c, line: 95

Fatal error:
More than 9 graph edges per atom (atom 16)
----------------------------------------------------------------

Its a rather complex molecule with lots of dummies attached,
the molecule itself has 7 atoms and 15 constraints are specified,
so it should be ok.  Again, it runs fine in the gas-phase with pbc=no
Has anyone else run into this?
Thanks
Jim Rustad
