Thanks for taking a look. That matches what I'm seeing, which is that RAM usage of shibd always goes up. Traffic peaks at night, then goes down in the early morning each day, but over the course of a week or so, memory usage of shibd only goes up and never seems to level off as I would expect. We didn't see this with shib1, so I assume the issues you mention didn't exist there?

I guess that depends on how many new sessions we're seeing and how much RAM there is? Could you estimate how much RAM per session we're talking about?
