Do you have a line that looks like: hp.add_halo_filter(HP.VirialFilter,must_be_virialized=True, overdensity_field='ActualOverdensity', virial_overdensity=200, virial_filters=[['TotalMassMsun','>=','1e14']], virial_quantities=['TotalMassMsun','RadiusMpc'])
If so, please post it. The number of halos > 10^14 Msun is fairly close to 500 in a 200 Mpc box. If you want the halo profiler to use all halos, set virial_filters=[['TotalMassMsun','>=','1e14']] accordingly.

Do you remember the cosmology parameters for your run: particles, grid, box, refinement, AMR ON or OFF ?
I have run a 200 Mpc/h box, 512^3 particle, 512^3 grid, AMR-OFF simulation and I get about 30,000 halos using HOP. When I try to finding virial halos, I get only 500. I may have to increase the grid to 1024^3.
Let me know how you got 40,000 virial halos.
