That's odd.  I would check how you have Keep-Alive configured and how
long you let the mod_perl processes live (MaxRequestsPerChild) in both
cases.  Nginx should be just fine as a proxy.

It's mod_proxy configuration.  There are lots of guides on how to do
it, including some on the mod_perl site.  Search for mod_proxy or
reverse proxy.
