Error when updating feature layer

CIDAdmin

I have always used the Python API to update a feature layer with no issues. 
Now I'm trying to update it and it keeps failing with this error. Last week it was only for a few features, today for all of them. What is happening?
Is there a way to investigate further besides this error message?

{'addResults': [],
 'updateResults': [{'objectId': 1,
   'uniqueId': 1,
   'globalId': None,
   'success': False,
   'error': {'code': 1000,
    'description': 'Cannot create a row of size 8405 which is greater than the allowable maximum row size of 8060.The statement has been terminated.'}}],
 'deleteResults': []}

You should try to figure out what row is.  What data are you updating in the feature layer and is it appending to the existing data and creating a longer row each time for that 'row'?
