DeserializeJSON - is there a limit on the size of the JSON data that can be converted?

I have some valid JSON data that's being converted successfully by DeserializeJSON... until it gets to a certain size, or that's certainly what appears to be happening.  The breaking point seems to be somewhere in the neighborhood of 35,000 characters... about 35KB.  When the conversion fails, it fails with a "JSON parsing failure: Unexpected end of JSON string" message.  And when the conversion fails, the JSON data is deemed to be valid per tools like this one:  http://www.freeformatter.com/json-validator.html.

So, is there a limit on the size of the JSON data that can be converted by DeserializeJSON?

Thanks!
