I don't see any obvious problems.

Clients don't know which server is primary and which is secondary.  They
initially try them in an arbitrary order; if the first one they try doesn't
respond, they then try the other.  Over time they learn which one responds
more quickly, and keep using that one.  Since your secondary server is
dead, they should learn quickly that they should only use the primary, so I
don't think this should be causing your problem.
