You are getting multiple responses from the ping

can you ping the IP with the following from the XI server to see if you get duplicates

Code: Select all

ping ip_address

From the ping man page:

DUPLICATE AND DAMAGED PACKETS
ping will report duplicate and damaged packets. Duplicate packets should never occur, and seem to be caused by inappropriate link-level retransmissions. Duplicates may occur in many situations and are rarely (if ever) a
good sign, although the presence of low levels of duplicates may not always be cause for alarm.

Damaged packets are obviously serious cause for alarm and often indicate broken hardware somewhere in the ping packet's path (in the network or in the hosts).

You may want to check with your network to see if there is something going on or if it was a temporary problem.
