Hi Eric,
It sounds like there might be a problem with the 'upload' profile, but it's not immediately clear what that could be.
What does:
SELECT * FROM sp_get_last_synchronize_result();
return after this error from the 'SYNCHRONIZE' command?
What does :
SELECT * FROM SYS.SYSSYNCPROFILE;
return for this database?
Regards,
