Been through that. In my case, iy appeared to be due to users hitting
the 'back' button of their browsers up to a (customized)  login  page,
then starting a new session under another account without logging  out
from the previous one. Since we've managed  to  pass  the  information
that  clicking  'logout'  was absolutely mandatory to switch sessions,
there has been no new report.

Hope it helps.
