2503/WS-1103 intermittant ping

I installed a 2503/WS-1103 which is a catalyst 3200 with a router
blade installed on my network. The router seems to perform OK except
when I ping the ethernet connection, I only get back every other ping.
The 7 cisco 2500 routers are connected in a circle using serial
connections. Also, there is only one gateway listed in the "sh ip
protocols". All other routers in the circle show two gateways listed
in the "SH IP protocols" display. Configs listed below.
