How does Passivation Daemon works ?

Today we setup two new nodes in production, to serve Mashup(IAC) traffic exclusively.The passivation Daemon last run time showed ok unti 3:10 am , but that's the latest last run time. The amount of stale requestors have increased exponentially which forced us to restart nodes to be on safer side at around 4 pm - No out of memory exceptions occured.

While monitoring now at 7 pm, I see the last run time ok - on the busy node. However on the second node - which is less busy and hardly has 10 requestors , it shows passivation daemon's last run time as 4:20 pm.

There are no exceptions in logfiles of any node.

So my questions are:

1) How Passivation Daemon is supposed to work?

Does it wakes up in regular intervals or any other pattern or it wakes up only if it has certain number of pages/requestors to be passivated ?

2) What makes it to fail ?

Thanks.

I reviewed the posts below, but none of them helped.
