Hi Rudolf,

I can only indirectly address your question so it might not be helpful.  I
am very actively using a descendant of Aida and haven't had any issues as a
result of the new year.  The nonexistent context error *normally* only
occurs when a session is killed / times out but a page based on that
session is already loaded in your web browser which sends an event (as the
result of an action such as a button click or some running browser-side
Javascript code) which results in the server needing to locate the session
in order to respond.  I can think of a couple of ways a year rollover might
result in this sort of error:

1) There could be a problem with the expiration date for Aida-generated
cookies.  If the expiration date is hard coded to an expired date, the
browser would likely immediately discard them.  The net result would be
that when the browser needs to pass the session id back to the server, it
doesn't have it to send. (I *think* that's how Aida handles the session id
by default but it's been a while since I've run a 'regular' Aida server)

2) There could be problem with the session cleanup logic incorrectly
terminating sessions too quickly (or even immediately) on the server.  So
be on the lookout for any funny looking date logic/math there.
