Hi, we tried upgrading 5.0.16 FOSS to 6.0.0 FOSS. After running the upgrade script without errors, we ended up having the following problems:
* Web interfaces hangs loading after login (AJAX and HTML versions), both the standard user interface and the admin one.
* The zmmailboxdmgr java process eats up 100% CPU everytime.
A clean installation of Zimbra 6 on Ubuntu 8.04 LTS in the same configuration works ok, so I guess this is a problem generated by the upgrade. Any suggestion?
