Hi,
I searched the forum but did not find a good answer.
I'm using an ecosCentric port for maybe 2 years now. My TCP apps kept
running out of sockets so recently I increased the sockets and open
files (seems like it needed both to work) and the socket issue seems
solved. However, when the system runs for a day or two it no longer
responds to network packets. "Out of MBUFs" prints out the serial
port
and only a reboot fixes it. The BSD stack does not recover. Can
someone point me at a fix I have overlooked/missed.
My first guess is your Ethernet driver has a bug in it and is
causing an MBUF leak. For example: under some obscure
condition, the Ethernet driver never notifies the network stack
that a particular packet has been sent. The MBUFs associated
with that packet will never get free'd, and you eventually run
out of MBUFs.
Many years ago (eCos 1.3.1), using the old network stack I also
saw out of MBUF errors occur because of a race condition in the
network stack. I have a hard time believing there are too many
bugs like that left unless you're doing something pretty
strange.

I had not considered that the Ethernet driver might have a problem
because it had been working for so long without an issue. But maybe it
was never being stressed - I'll have a look.
