Dear Dirk,

as you realized that warning is not lethal.

The max angle you requested (5 deg) is pretty small and, combined to the
small value of the minimum sub-step length, implies for (very) low energy
particles too many sub-steps that would exceed the hard limit of 2500, to
which the tracking is then anyhow constrained (the last sub-step gets
longer). Increasing that limit (something that - as previously discussed -
you cannot do) and approaching it often, would have a dramatic impact on
CPU time.

You may want to relax the above mentioned parameters (considering that
they apply to charged particles of all energies). Anyhow you can live with
this warning, knowing what it means

Best regards

Francesco
