Hi all,
I have done some more investigation and stumbled into something odd.
If I use ping currently I am getting about 3% packet loss (it gets worse)
but with hping (to the exact same ip) I get no loss?
As I understand hping and ping use different methods of sending packets,
could this be an indication to where my problem might be (buffering or
something) ?
Ping --
290 packets transmitted, 281 packets received, 3% packet loss
Hping --
289 packets tramitted, 289 packets received, 0% packet loss
I'm using icmp mode in hping, and sending to the same ip...
Thanks again for the help
Dave

Hi,
Its interesting you'd say that I'd virtually ruled it out given that
it takes over a day to start? What I do see sometimes is a message warning
me that its limiting open port RST responses - the unit is under a
reasonable amount of load though (but not overloaded). The strange thing is
that its open port (not closed). Even if I up the limit though (the messages
do stop) it doesn't stop the dropping...
I've rebooted it recently, but here is the dmesg --
