We have more then 10gb of free disk space. No, I reached the session 
objects limit. It was set as 10000, now I set it as 50000, and the counter
is going higher every day.

Yes, I packed it, size reduced, but the number of session objects still
the same. And keep growing.

Today morning stats (nobody works now, people still slepping at England):

 12567 items are in this transient object container.

 Data object timeout value in minutes: 20

 Maximum number of subobjects: 50000

Yesterday there was only 10000 session objects. Now, I am packing ZODB:

--- before pack ---
 Database Location: /home/zope/current2/var/Sessions.fs 
 Database Size: 6.2M 
 Transient Object Container at  /temp_folder/session_data
 12568 items are in this transient object container.
--- after pack ----
 Database Location: /home/zope/current2/var/Sessions.fs 
 Database Size: 59.8K 
 Transient Object Container at  /temp_folder/session_data
 12570 items are in this transient object container.
