Harshal,

You are using Raspberry Pis, right?  Some Raspberry Pis have a problem
with the power supply, where the wifi interface will go down and back
up when under load.  Since Babel flushes the routes that go through
a down interface, this would explain your problem.

Are you absolutely sure that the wifi interface does not go yo-yo
(down and then up) at the time at which you lose all of your routes?
