<DIV><FONT face=Arial size=2>Hi.</FONT></DIV>
<DIV><FONT face=Arial size=2>From time to time I encounter this problem. It
occurs mainly at some remote installations while everything may work at the
lab. I take it as inevitability and use external reset monitor to reboot the box
for such a case. </FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> [En-Nut-Discussion] ethernet
connection down </DIV>
<DIV><BR></DIV>I am running an ethernut 2.1B connected to the internet with a
static IP. I have also tried an ethernut 2.0A and this seems to exhibit the
same behavior. We access the webserver periodically every minute to get data
posted on the webpage. The httpd and telnet threads we are running are pretty
much copied from example code. After several hours of normal operations (4 to
6 usually), the ethernut is no longer accessible over the network. All the
LEDs are showing activity, but any incoming connection will time out, no ping
etc. I set up a serial port thread to check the threads with
<TT>nutThreadList</TT>; all are listed as OK and appear normal. The
NutHeapAvailable is around 18k. I can then reboot over the serial port (or by
power cycling) and the ethernut will be available again over telnet and http.
This problem is periodic, but it takes several hours to crash, and not
everything crashes, so the watchdog timer is of no use.<BR><BR>Has anyone seen
this problem? Does anyone have any suggestions on methods to figure out what
is going on here?<BR><BR><BR>Cheers,<BR>Peter<BR><BR><BR>Peter
