<DIV><FONT size=2>Hi Eric</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>When I first had this problem with version 4.4.23, Dave,
W9ZRX, was looking at the ARC log, and reported to me that I was not sending the
pings. When I looked at the spider debug log, I could see that I was
sending them. Evidently ARC was throwing them away before they were being
logged. Comparing the two logs gives a better picture.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>As I understand what happened in version 4.4.23, a copy of the
last packet received from a node was compared to the next incoming packet.
If they were identical, then the incoming packet was thrown away. If the
link is busy with PC19s, PC16s etc, then there might never be a problem.
When all you send out on the link (like I do) is the every 5 minute ping and an
every 14 minute PC50, two in a row pings can get tossed into the bit
bucket. Increasing the obs count will get past this, but your
round-trip-times will look terrible. I ended up changing my PC50 times to
every 5 minutes. This logic also caused havoc with mail longer than 9
lines. The PC31s were getting discarded and the mail hung. (BTW,
this has been fixed in 4.4.24)</FONT></DIV>

<DIV><FONT size=2>I have no idea what Terry did in version 4.4.24, but it has
not really cured the problem.</FONT></DIV>

<DIV>Hi Tom </DIV>
<DIV> </DIV>
<DIV>I have a Spider node that was disconnecting every 10 minutes with a
new version ARC.</DIV>
<DIV> </DIV>
<DIV>I did an extensive test with a 4.4.24 ARC and my Spider
cluster and Spider did not send a ping to ARC during the 25 minute
test period (it was sending pings out on Spider links). It did receive
pings every 5 minutes from the ARC and ignored every other one. I was
getting disconnections every 10 minutes so I re-did the test
after setting obs to 3. This time the unanswered ping dropped the obs
count to 2 and the answered ping returned the count to 3 with no
disconnection. It therefore appears for me that Spider doesn't ping
ARC and it disconnects a link with ARC on the next ping following
the obs count reaching 1 instead of zero. </DIV>
<DIV> </DIV>
<DIV>So, oddly my result is different to yours. I can stay connected by
increasing the obs setting. This is weird.</DIV>

[Dxspider-support] disconnects from ARCluster nodes</DIV></DIV>
<DIV> </DIV>
<DIV>New ARC software was installed on N3RA, the node I connect to, last
night.</DIV>
<DIV>Version 4.4.24. Except for the very first ping right
after initialization,</DIV>
<DIV>my pings to N3RA are not answered. Setting OBS higher no
longer works. I</DIV>
<DIV>tried it at 4.</DIV>
<DIV> </DIV>
<DIV>I have turned pinging off (set/ping 0 n3ra) in order to stay
connected.</DIV>
