This won't help.

There already *is* a primary key on the turba_objects table.

object_uid uniquely identifies the contacts.

This is not supported via ActiveSync, the protocol was not designed  
for large, bulk updates like this from the client. Even with a true  
Exchange server this number of contacts wouldn't work. Unlike the  
server -> client response, there is not "MOREAVAILABLE" tag in client  
-> server requests to split the updates. Most likely your request is  
either timing out or hitting a memory limit. You should instead import  
the vcard file directly via Turba.
