Question on r-queue from vmstat out
On our prod system we found sometime runqueue goes back to 0 as below.
Whereas on test server even with very very less work the r-queue never dropped to 0. Under what conditions r-queue drops to 0? Does it mean something unusual?

EG:
Code:
kthr    memory              page              faults        cpu       time  
----- ----------- ------------------------ ------------ ----------- --------

qstart

qstart(8B)								PBS								qstart(8B)

NAME

       qstart - start pbs batch job processing at a destination

SYNOPSIS

       qstart destination ...

DESCRIPTION

       The  qstart  command directs that a destination should process batch jobs.  If the destination is an execution queue, the server will begin
       to schedule jobs that reside in the queue for execution.  If the destination is a routing queue, the server will begin to route	jobs  from
       that queue.

       In order to execute qstart, the user must have PBS Operation or Manager privilege.

OPERANDS

       The qstart command accepts one or more destination operands.  The operands are one of three forms:
	    queue
	    @server
	    queue@server
       If queue is specified, the request is to start that queue at the default server.  If the @server form is given, the request is to start all
       queues at that server.  If a full destination identifier, queue@server, is given, the request is to start the  named  queue  at	the  named
       server.

STANDARD ERROR

       The qstart command will write a diagnostic message to standard error for each error occurrence.

EXIT STATUS

       Upon successful processing of all the operands presented to the qstart command, the exit status will be a value of zero.

       If the qstart command fails to process any operand, the command exits with a value greater than zero.
