Is there any limitation for binding thing properties

Hi,

I create a thing in ThingWorx Composer, and try to bind remote properties with the thing properties; it works fine when there are 300 properties,

but then it's more than 400, error reports:

"Error：Unable to bind things: error to trying to process message: context cannot accept multipart messages bindrequestmessage"

Does anybody know why this happen? Is there any limitation for the number of properties bound to remote thing?

Thanks,
