Your broadcast addresses are incorrect for your subnets.  eth0's
broadcast should be in the range of 214.74.101.112 to 214.74.101.127
(most likely 214.74.101.127).  eth1's broadcast should be in the range
of 214.74.132.16 to 214.74.132.31 (again, most likely 214.74.132.31).
Having incorrect broadcast settings can cause all sort of funky things
to happen.

BTW, what hosts do you have directly in your two subnets?

HTH,
