Hello,
I've been running the sample galaxy and after a while i get the following error:

Begin Step 945, Time: 1.46332, Systemstep: 0.00152588
Start force computation...
Begin tree force.
tree is done.
force computation done.

Allowed region for isolated PM mesh (coarse):

Starting non-periodic PM calculation (grid=0).
Particle Id=37074 on task=0 with coordinates (-191.952|22.8454|7.37917) lies out
side PM mesh.
Stopping
In total 1 particles were outside allowed range.
task 0: endrun called with an error level of 68687

What would cause this and how would I fix it? I suspect that I may
need to change a value in the galaxy.param file but looking over the
documentation I still don't know what might fix this.

Thank you.
