check the logs? run strace on the process? run tcpdump on
the interface(s) to see what traffic it is trying to transmit?

Last I checked the 'metric' number in the linux routing table is
really only used when your using a routing daemon. as far as
default routes go, it should not have any impact.
I suspect the route is not the issue, I suspect that the app is
trying to talk to something external and then fails, it will fail
the same if you try to point it to a router that goes nowhere.
tcpdump should be able to tell you who the host is trying to talk
to. strace might reveal why.
