Hi all,
I am installing a zone onto two different V445s running S10U4 and the
zones are taking hours to install (about 1000 packages), that is, the
problem is identical on both systems. A bit of trussing and dtracing has
shown that the pkginstalls being run by the zoneadm install are making
door_call calls to nscd that are taking very long, so far observed to be
5 to 40 seconds, but always in times divisible by 5 seconds (5, 10, 15,
etc.), leading to the thought that it is one or more name service
timeouts. Eventually, once the door_calls finish, the actual package
install is very quick.
There may be a simple misconfiguration on both systems, but I can't
figure out what that might be. Additionally, I don't know why the
pkginstalls are making door_calls to begin with, and I'm not sure how to
figure that out. So that's one my main question:
*** How can I find out exactly what the pkginstalls are asking nscd
to resolve? ***
Hopefully that will lead me (and the Sun engineer with whom I have a
case open) to an understanding of what is leading to the presumed
timeouts.
FWIW, here's a partial truss with timestamps of an existing pkginstall
process. Once it hit the ioctl(3,...) it flew through the package
installation. Note the times around the door_calls: 13, 10 and 15
seconds (the first isn't a multiple of 5 since I started the truss
during the call).
Base time stamp: 1210181159.9172 [ Wed May 7 17:25:59 GMT 2008 ]
