I saw recently something which might be similar:

     All of a sudden, some "acl_users" objects went away.

     Of course, login via these formerly existing user folders
     were no longer possible.

     Restarting Zope solved the problem for some days. Then,
     the "acl_users" disappeared again.

Upgrading to Zope 2.5 *AND* Python 2.1.2 solved the problem...
It was almost surely caused by the known memory corruption
problems in Zope 2.4.x (with 1 <= x <= 3) and Python 2.1.1.
