So it is better with a larger setting?

In order to help solve this, way back when I set mine to:

session.gc_maxlifetime = 7200           ; garbage collection is now 2 hour
session.gc_probability = 25             ; percentage chance for gc each call

Not sure if that really helps, but it is what I used.

I don't think it means that sessions are killed when they reach 
gc_maxlifetime, I think it means at every maxlifetime interval it will 
try to cleanup sessions.  Not sure though -- I think I refered you to
www.php.net last time for details?  (Maybe I should look there too)

Yes, that is a problem.  Newer versions of IMP have much better handling
of this.  Each upgrade I've done made this better, and I've not had
any trouble/complaints for a long time now...  (Not like when 3.0 came
out and I was getting *lots* of complaints about this)

What version of Horde and IMP are you using again?
