:Yes, it is half-duplex.

I think there may be a problem with your hub setup (e.g. exceeding the
hub count or end-to-end length limitations) that is either resulting
in packet loss, or the packet burst is locking up the ethernet long
enough to cause a timeout. The problem looks very much like an
unrecognized collision to me.
I recommend replacing the hubs with switches. The whole topology will
be happier.
