I am using Drupal 6 with the Open Atrium distribution. Is there a problem if the same user connects from more than 100 different computers at the same time? At the moment I am unable to do a test but I would like to know if I can encounter any problem. So far I did try with 10 PCs and no problem whatsoever. Also is there a limit that I have to remove or by default there is no limit? Thank you.
