GoldenGate extract LOB datatypes encountering buffer overflow error

I'm trying to extract a table with LOB datatypes but encountering a buffer overflow error -- possibly due to the length of the LOB exceeded the LOB buffer size.  

Here's the error when running the extract process -

NLS_LANG         = "AMERICAN_AMERICA.UTF8" 

NLS_LANGUAGE     = "AMERICAN" 

NLS_TERRITORY    = "AMERICA"
