Bug

Global join operations on tables having repeating large varchars (larger than 256K chars) may lead to an internal out of memory and process crash. In this case, the query may crash with an internal server error. 

Fix

This internal process has been fixed to avoid these kinds of crashes. 

Workaround

Run the statement without selecting column(s) containing the large varchars
