Hi All,

I'm looking for a good sould that can spend 5 minutes to giv me more
details about some rec_controlll output. I already checked the reursor
static page but, unfortunatelly, it is not sufficient for my level of

*chain-resends* --> Is it the number of client requests arriving while an
outstanding request for the same requested RR is currently in progress
(querying remote NS)? (Think impatient Windows resolver client resending
requests too often)

*max-mthread-stack *--> Is it something related to thread? I have 4 CPUs
and configured 4 thread. Is it correct

*nsset-invalidations* -->

*sys-mse*c and *user-msec *--> What is the difference between them?

Thank you for your time
