First, upgrade to the latest Gromacs version. It takes care of lots of little
bugs. Perhaps not directly related, but you should always use the newest
version, unless you have a compelling reason to use an old one (i.e.,
consistency with previous work).
Second, your potential energy is extremely high. You have probably not done
sufficient energy minimization, which is causing your system to collapse
immediately.
