How to load-balance LotusNotes "Sametime" with CSS11500
I have 2 redundant CSS since a while, working fine. Recently I wanted to add load-balancing for the Chat service of LotusNotes Sametime. The problem is that the chat conversations are disconeected some how. On a first configuration, I didn't configure sticky mode on this content. Since then I added sticky mode "srcip" and a long sticky timeout (600 mn or 10 h.). But th eproblem is still the same. Can someone help ? Thank you. note : you'll find attached the configuration for the chat content.

The CSS 11500 uses the ArrowPoint Content Aware (ACA) service to gather response time data for every flow for building statistical averages/variances for every service and content rule. The best servers are used, while the slow servers are pruned from the eligible list. This service also can manage persistent connections for e-commerce based on IP addresses (range), Secure Socket Layer (SSL) application IDs, and cookies.
As you are having only 2 servers for load-balance.
As your keepalive time is 30 sec which is quite high.
I suppose you should change your keepalive frequency 30 to
keepalive frequency 5
using the default values of a 5-second keepalive frequency interval, a 5-second retry period interval, and maximum of three failures, a service can transition from the alive state to the dead state in 15 seconds; a 5-second interval between a keepalive response and the initial keepalive failure based on the keepalive frequency, and two failures, each occurring at 5-second intervals based on the retry period.
