I just reinstalled Zimbra 7.1.4 and need to import a large .tgz file (13GB) that I previously exported . However, each time I try this, Zimbra will only import less than 200 messages (a tiny fraction of the total) and then stop. There is no error message. I have tried this several times and the import process always stops there, even after waiting for more than 8 hours.

I have imported small .tgz file without any issues, which makes me think that this problem might be related to the size of the .tgz. file.

I really need to import this file and am out of ideas. Any suggestions would be greatly appreciated!

I'm using Zimbra Desktop 7.1.4 together with a Yahoo Business email account. I'm running MacOS 10.6.8.
