Hi,
I'm running haproxy-ss-20130509. I have load balancing set up with a stick
table using an application-generated sticky session cookie. This running
on two haproxy instances (with an Amazon ELB front-end).
I'm noticing that the server will occasionally change a mapping from one
server to another for no apparent reason. In other words, a given cookie
value will go to server app1, and then later it will switch over to app2.
The log doesn't show a DOWN message for app1.
What might the cause of this be? As I read the docs, the entries in the
stick-table are supposed to expire only after idle time - is that correct?
