target 11g source 10g on windows 2008

I have been using dpimp generally working / tested with tables up to 250m working in seconds

I am importing into a 11g environment with a user specially created

I am sometimes getting blocked by wait events on source database

with control file parallel write or log file parallel write

So some tables work & others just cause the job to hang with sessions in source database causing the above wait events.

Is there anyway I can set up my dpimp param file ( see below )to avoid these
 / my instinct is that the fail is because of other parts of new environment being missing ?

Should I turn parallel off or is this a red herring?

Any help will be gratefully ( in solution or approach) received as I am near to my wit's end !!
