Yes, they indicate that the fileserver cannot contact that client to
tell it that the files have changed (well, the latter two, anyway). Is
that client behind a NAT or some kind of stateful firewall? Assuming
not, a simple test you can perform to check that a client is reachable
from the fileserver is by running:

rxdebug <client> 7001 -version

from the fileserver. If that does not respond with the version of that
client, check firewalls et al and allow port udp 7001 to the client.
This is assuming, though, that the client generally stays up. It can be
normal to see messages like that if the client is abruptly removed from
the network or shutdown in an unclean fashion, etc.
