Tapestry manages persistent state in the HttpSession. As of 5.2, it doesn't do anything special to handle cases of multiple requests (perhaps due to Ajax) attempting to modify the same SSO in multiple threads.
This aligns with Brian Goetz's observation that all stateful web applications are inherently broken: http://www.ibm.com/developerworks/library/j-jtp09238.html I'm not aware of any concerns. You may want to have your SSO implement the HttpSessionBindingListener interface, and log the details of when it is bound (saved to the HttpSession). That might illuminate what's going on. It may be a bug in your servlet container, it may be a race condition between threads, or it may just be a coding problem in your code. I hate to say it, but the last option is the most likely (given the total lack of information you've provided).
