It is possible that you're seeing the effects of a bug in the
bonding driver, if your kernel does not have the upstream commit
1899bb325149 ("bonding: fix state transition issue in link monitoring")
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/drivers/net/bonding/bond_main.c?id=1899bb325149e481de31a4f32b59ea6f24e176ea
I don't know if or when this fix was incorporated into the
debian 4.9 kernels.
