What do you mean by 'after kernel sample overflow'? Another key point, with IBS you cannot filter by priv level, it captures instructions at all levels. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
