What exactly do you mean by on the "same subnet".  On the same
physical network?  Are you dual subnetting (running two different
subnet address blocks on the same physicial link)?  Or are you really
running the same subnet and trying to split traffic across both cards?

Perhaps just the output of these files will help:
   /etc/sysconfig/network-scripts/ifcfg-eth0
   /etc/sysconfig/network-scripts/ifcfg-eth1

As well as any other advanced settings you may have made,
especially routing-related settings.

Also try running this command
   /sbin/ip route list
both before and after you take down eth1.
