I had this problem also with the debian package in squeeze and I thought
it was dued to the number of users I had, more than 3 thousand however
it happends the same with few users.

I saw the package was a very old version of CalendarServer (1.2) and I
decided to compile the subversion trunk what it was very hard but at
least, after more than a week I could do it (I had to download a couple
of things manually, ez_setup and Twisted, if someone need more details
how I do it let me know). However in the 2.2 and 2.3 versions and also
in the svn trunk there is not possibility to use groups
(http://trac.calendarserver.org/ticket/330 ) something I don't
understand and which is very important for me and right now I'm stopped
for this reason.
