Related to reducing the likelihood of a backlog of transmits at 1G, try
Disable TSO - ethtool -K eth0 tso off
Reduce TX descriptors - ethtool -G eth0 tx 64
I would try the first by itself, then try the two combined.
Hi, thanks for the suggestions. Hardware info included. Now running
since yesterday (I had a hunch tx descriptors could affect things) with
"Current hardware settings:
RX: 4096
RX Mini 0
RX Jumbo 0
TX: 1024 "
and since this morning TSO disabled with no errors. Trying with 64 if
the errors reoccur. If problems continue, will try replacement switch
(or understanding the exact limits of current switch and working around
them, in this application pretty much everything except resetting &
stopping all traffic 5-20 seconds when an error occurs is acceptable)
