Subject: AMBER: Binding free energy errors: Grid setting fail

Dear amber users,

Did anyone found this similar problem ? I got some errer after performed
mm-pbsa for calculating the binding free energy. The error shown some
mistake in trajectories 2 as follows:

       /AMBER/amber9/exe/pbsa -O -i pbsa.in -o pbsa_com.2.out -c
../01_generate_snapshot/snapshot_com.crd.2 -p ./enz-lig.top not successful

When i check the output file of pbsa_com.2.out which you can see below. It
seems like the problem from setting grid. And the output of the
snapshot_com.all.out stop at trajectories no.2 which indicate some unknown
parameters or the maximum of somethings.

So, anyone who had been experienced for this problem like me, please give me
some suggestions to solve. That would be grate for me.
