Symptoms:

When inserting a record into a replicated table, the following SQLServer error message can appear:
"Length of text, ntext, or image data (x) to be replicated exceeds configured maximum 65536"

Example error stack:

Message :Length of text, ntext, or image data (96491) to be replicated exceeds configured maximum 65536.
The statement has been terminated.

The insert is unsucessfull.

Cause:

Replicating large amounts of data will introduce latency. To prevent this, SQL server caps how much data can be replicated in a single column using the Max Text Replication Size setting. This setting has default value of 65536. If you try to replicate text data which exceeds this length, you will get the error message stated above.

Resolution:

You can work around this situation by changing the setting 'max text repl size'. You can do it, using a SQLServer stored procedure called 'sp_configure'.

Example Fix:
EXEC sp_configure 'max text repl size', @NewSize
RECONFIGURE WITH OVERRIDE
