usually your operating system will delete all routes (so olsr does not
have to do it)
i supsect following, the interface is taken up/down so fast that olsr does
not detect it (it polls the interfaces and has no callbak from the kernel
to get notified instanttly)
so if the interface is up too fast, olsr doesn`t detect that it went
so it will not reinsert the routes the operating system dumped when taking
the interface down

It used to be a known effect, but should be fixed since around 9 months,...
but (i just read your email again) olsr-0.5.6-r3 it that old that it could
still suffer from this bug,.
so use a newer olsr (0.5.6 r5 or r6 (next week))

remove/replace the other program,..
or delay its operation
i suggest to test following:
check if you have routes
take the inteerface down by hand
wait 5 seconds
take it up again
check if the routes come back,..
