SRCB6005121

Error Description

Client system crashed twice during normal operations both were  
word 1 B6005121 additional words were different. The two        
crashes were both related to heap allocation. After            
investigation it was found to be related to the combination of  
a query with UNNEST and DBMON is active. Odds of having a      
problem get higher when the array name is longer then 16 bytes.
