Hi Marco,
I think the easiest thing to start with is to run "netstat -atn" on the
backup node to verify if the peers connection is always between the same
two ports or if it changes, indicating a reconnection.
Hi, Willy
I did not find yet the 1.5.11 package to test the older version, but I
hope that the 'netstat' output is interesting.
All IP are owned by 10.64.38.1 that manages all traffic while haproxy on
10.64.38.2 does not receive any connection.
I rebooted 10.64.38.2, then I launched two 'netstat -atn', one 5s after
the other. The output is filtered and sorted.
Hope this helps
Thank you a lot
