High retransmissions, check TCP patch level

But I only had a 1.2% collision rate as reported by netstat -i

Basically I was told that Adrian's default parameters are very low and what
I was seeing wasn't really a problem at all.
No one knew what "check TCP patch level" referred to.
However, this weekend I was upgrading a HPUX 10.20 server and added it to
the FDDI backplane of the switch, and I noticed what appeared to be network
loop between the LAN and FDDI interfaces of this HP. The switch went mad and
locked all segments solid. Since we already had one of these boxes in this
config, it is very possible that we had a network loop somewhere...
Broadcast storm I would guess...
Whether this would cause "high retransmissions" or not, I don't really know.
