GuitsBoy, do those errors really correlate to an observable problem, like users being timed out unexpectedly?
It’s just that as I review this thread (opened in April), I’m left wondering now if it could be the exception message (reported by you and Lynux, the OP) might simply mean that by the time one instance tries to replicate its session data to another instance, the session (for that sessionid) on that other instance has simply timed out. That’s what “invalidated” means. I’d never really considered it before. But since the error says it’s trying to do a “remoteAttribute”, indicating that the one instance is telling the other instance to remove a session or key in it, maybe that’s all that this message means.
But I see that Lynux has in fact followed up your note. And I’d like to not ask them this same question (I hope they’re reading this) but I’d also follow up with just a little more back to their original post. And maybe what I ask them there may help you, too, Guistboy, in resolving whatever may be your real problem.
As always, just trying to help.
