I can't seem to avoid getting exceptions when importing an MLCP archive. It
consists of a root folder and two ZIPs, each about 190MB, and it was exported
from ML 8.0-3.2 on Windows using MLCP 1.3-3. I imported this into a Mac running
the same versions of ML and MLCP. All of the source documents appear to have
been imported successfully anyway, regardless of the errors, but is there
something I should be doing differently to prevent this?
$ mlcp import -host localhost -port 10003 -username admin -password ********
