Chris McDonough rewrote the Transience implementation...maybe this solves your problem. I think the new implementation is on the CVS HEAD.

 Tested configurations for /temp_folder/session_data :
 *****************************************************

 1. timeout value in minutes : 0 (= infinite)
    max. number of subobjects: 0 (= infinite)

 2. timeout value in minutes : 20
    max. number of subobjects: 50'000

 3. timeout value in minutes : 20
    max. number of subobjects: 1000

 Questions:
 **********

 - is this a known problem?
 - is there a known way to solve it?
 - is it a server config or a Zope or a CMF problem?


 Thanks very much for an answer. PG
