In updating one of our authoritiative name servers to 5.2-REL, we enountered 
after two days of running, kernel message like:

kern.maxpipekva exceeded, please see tuning(7).

appearing to the point to where you couldn't ssh into the box (because sshd 
died w/ too many files opened).  I see so mention of kern.maxpipekva on the 
tuning man page, and greping only finds kern.ipc entries.

% sysctl -a | grep pipekva
kern.ipc.maxpipekva: 10485760
kern.ipc.maxpipekvawired: 5242880
kern.ipc.pipekva: 131072
kern.ipc.pipekvawired: 0

Are they the same, and if so, what's are the guidelines for increasing the 
number?

Best Wishes - Peter
