[Xymon] Unexpected times on "Connection Times" graph

Here is a "connection times" graph from Xymon:


This shows "conn" times in the 40 millisecond rang, and "ssh" times in
the 200 microsecond range.

What is the source of the "conn" graph?  I would have guessed ICMP, but
it doesn't make any sense for a ping to take longer than an ssh
connection, especially not that much longer.  This is what I get if I
ping that machine from the xymon server ... it doesn't take anywhere
even CLOSE to 40 milliseconds:

[root at mcp xymon]# ping palazzo
PING palazzo.REDACTED.com ( 56(84) bytes of data.
64 bytes from palazzo.REDACTED.com ( icmp_seq=1 ttl=62

5 packets transmitted, 5 received, 0% packet loss, time 4003ms
rtt min/avg/max/mdev = 0.572/0.645/0.890/0.126 ms

Can anyone shed light on this?  My server config includes the following


My xymon server is version 4.3.14.
