mdrun -h tells you how it works.
You should send a signal to one of the child processes (not the parent).
As fas as I know this works fine under lam-mpi.
I don't know what you mean exactly with "in a PBS environment". But you will
need to send a kill signal to a child process on the node it is running on.
