I am writing a network IP device monitoring program in Tcl using the
Tnm
(Scotty) libraries. The following is a sample of my code:

set ping [icmp -retries 4 -timeout 8 echo $dev]
# then parse out the result so we see its response
set pingresult [lindex $ping 0]
set responselist [split $pingresult " "]
set updown [lindex $responselist 1]
# if device reports as down
if { $updown == "-1" } {
# do stuff
}

The program works great for a few hours then strange things occur. The icmp
echo will return false results (positive round trip times) when I know for a
fact the device in question is NOT on the network.

Has anyone experienced similar results? Is there a solution?

I am using release Scotty v2.1.7.
