We're using Zimbra 5 (RC2) and doing a fair amount of migration testing where we are creating and deleting accounts regularly. It appears that once we reach our license limit (400) we cannot add new accounts until we restart zimbra. So we'll reach the limit, then delete all but 10 of the accounts and try to recreate them but we get an error about reaching our license limit. Viewing the license tab in Global Settings also shows 400 accounts have been used. Viewing the Accounts page however shows only 10 accounts.

Once I restart zimbra the correct numbers are displayed. Anyone have any ideas here?
