We keep getting the message: "attempt to xmit but no xmit i/o buffer"
for our bf0 (FDDI) interface.
I have changed "bufhwm" in /etc/system from the default 2% to 10% of
the RAM (512MB). The message is still coming, sometimes right after
"boot -r" when there is only a few login users.
This happens at our Sparc1000 with 8CPU and 512MB running 2.3 at 101318-42
Anybody knows how to fix this problem? how to monitor how much buffer
has been used?
