Hi all, I have a site which is using userdb to authenticate. People authenticate happily and can use the material ok, but will get logged out pseudo-randomly. This is evidenced by someone clicking a link, then clicking it again and again (not rapidly). They will then get logged out after a randomly selected number of clicks. This is really weird - I've never come across this before using UserDB (1.3.0). This is on a Zope-2.2.4 and Zope-2.3.0 system under Python 1.5.2 with Solaris. If anyone has any clues please let me know as this is driving my user batty...
