Hello,
I set up a small cluster with LVS (IP Tunneling) and 3 Apache nodes.
All was working fine, but since tuesday I have a strange behaviour :
some of the HTTP requests are sent to more than one node !
I use wlc scheduler, and actually the 3 nodes have the same size.
Do you know what is my error ?
I extract a part of log files (see bottom) : we can see than requests for
node 1 are ok. But when a request is for node 2 or 3, then both servers
receive it.
