After upgrade from 6.0.4 NE to 6.0.5 NE running on Ubuntu 8.10 LTS the multiserver install fails to run the stats process on the ldap and mta servers (running OK on the store). Running "zmstatctl start" appears to want to start the process but then requests a sudo password for zimbra user. I've checked the sudoers file and found it necessary to add:

%zimbra ALL=NOPASSWD:/opt/zimbra/libexec/zmstat-fd *

Then "zmstatctl start" starts the stats process.

Hope someone else finds this useful and solves their problems.

Release 6.0.5_GA_2213.UBUNTU8 UBUNTU8 NETWORK edition.
