Re: [Gems-users] Problem with XACT_MEMORY set to true in Gems 2.0

[Luke Yen <lyen@xxxxxxxxxxx>]

Hi,

  Can you try to perform the same tests using our latest GEMS 2.1 
release, and report your results?
  This error might be due to a protocol bug that was fixed in our latest 
release.
  Thanks,
    Luke
