stats problem

[mikets]

The os server version is debian 3.1
The zcs version is 3.1.2
Configuration in multi-server, all service of one server except the mta service.
The web admin stats page for "message count" "message volume" and
"anti-spam activity" is blank.
The server works since more 48 hours.
I have zmsyslogsetup launch on all servers

No error in /var/log/zimbra.log
No error in /tmp/logprocess.out and /tmp/gengraphs.out


How to resolve this problem?
Thanks!

There is a bug with multi-node setups where the stats won't display. This should be resolved in a future release.
