I put Zimbra in a test server:
- Ubuntu Dapper Drake 6.0.6
- Pentium IV running at 2,8Ghz
- 512MB RAM
my problem is that with only three active users and 48 total messages (of these three users together), Zimbra is sucking CPU at 100%.
I really don't understand why is happening this. I tried to disable antispam and antivirus, but it doesn't solve the problem.
