Abaondoned addresses are only used as a last resort (the server will
prefer in decreasing order: unused addresses, previously used but now
free addresses, abandoned addresses) - so the fact that it's being
reclaimed suggests you are out of available addresses. Make some more
addresses available, or remove some clients, and I suspect the
problem will disappear.
My guess would be that there is a device using 192.168.194.20 that
shouldn't be, and so any client offered that address is unable to use
it. The first is able to decline it, but the second is silent and
just goes back to get a different one.
