You were exactly right here. Moving to the filters instead of the
iptables classify solved the issue. As for performance, I have not yet
benchmarked it to determine if the filters are fast enough for the
number of users I need this to support.

I doubt that's the issue.  I do however recall there being issues with
using iptables classify to targets that were more than 1 level deep in
the tc qdisc hierarchy.  In such situations it works much better if
you instead use a tc filter on the mark instead of an iptables
classify. Is there any particular reason you're using classify on a
mark instead of a tc filter on the mark?
