Re: Users losing session on 11500 series Content switches

the CSS has an aggressive way of destroying idle connection.

If a connection stays idle for 8 sec, the CSS mark it has idle.

Once marked idle, a connection will stay idle forever for the CSS - even if traffic is still going on between client and server.

So at some point of time, the CSS will decide to reuse the memory used to switch a connection marked idle.

At this time, the user will lose his session.

The solution is to increase the idle timeout.

The command is 'flow-timeout-multiplier' and you configure it per content rule.

Give it a try with a timeout multiplier of 20 and see if this improves the situation.

You may have to increase the value.

Gilles.
