Identified
We have identified a problem were some users will be logged out for no reason as they are moving through the site. Also a related problem were calendar settings are getting reset.
We have identified the underlying problem which was caused by a full cache, that holds our authorization information, which is causing dropped data which causes the log out problem. Simiarly calendar settings might also be dropped in the same way. We are in the process of increasing the size of the cache so this problem should go away shortly.
