It does have a way of rate limiting per user, check the docs. :D

Dave,

How many logins?
We recently had a misconfugured cas client from a vendor almost fill
/var.  It was tens of thousands of logins.

It would be nice if cas had some way to rate limit ST and login requests
per user.

Thanks,
Carl

    I'm not sure how or where you would mark this as a singleton
    instance - although if you go back to an actual Google web page
    multiple times from the same browser session you reuse the ST if
    that's what you mean.  This actually looked like multiple logins
    from a single user over the span of about 30 minutes.  Not sure if
    this was some poorly written webapp logging in several time or what.

    Rapid heap memory consumption (which are not garbage collected)
    *can* be caused by unfinished Spring Webflow flow sessions; this
    is something we have observed. However, when looking at your
    memory dump, the majority of the instances (and size) is being
    claimed by the GoogleAccountService. Perhaps this is not marked as
    a singleton instance?

        All,

        Yesterday evening one of our CAS 4.0.0 servers went from under
        a GB of heap usage to 3GB in a matter of about 10 minutes.
        The end result was that again the SSO service died (one server
        with a heap memory OoM error and the other trying to replicate
        the ehcache to the dead server.  This was definitely not a
        memory leak issue as the servers had been restarted only
        earlier that morning, so they had only been up for about 17
        hours or so.  Out system monitors also indicated that the
        memory usage rather suddenly skyrocketed (over the course of
        about 20 minutes) so we suspect that the memory consumption is
        a symptom of some other issue.

        We have a heap dump but I am having a bit of trouble trying to
        analyze it with jvisualvm as I have never used the tool
        before.  If I am interpreting the dump correctly, it appears
        that tickets only play a very small part of the overall memory
        usage (see screen shot).



        Has anyone heard or experienced anything like what we are
        seeing?  This is becoming increasingly frustrating as every
        time we think we have the issues resolved and turn our
        attention elsewhere one server or the other crashes and takes
        the service down with it.

        Dave
