How do I stop reading of detail file after a certain threshold is reached

[Vivek Mehrotra]

Thanks Alan and Fajar,
How do I ensure the buffered-sql file gets included by the server? Do I need an additional default Virtual Server configuration to enable the buffered-sql?

Where are the SQL queries picked up from if there is no buffered sql? 

Also, how does dialup admin interface pick up server/sql information if I wish to incorporate that in the product?
Thanks in advance,
vivek
