How to print kernel global variable.
...some info that dtrace can print out kernel global variable, so what am I missing here? -- blu "Remember ''A Thousand Points of Light''?

Slow pkginstalls due to long door_calls to nscd
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

dtrace and follow fork
I am trying to use dtrace to trace all sscanf calls. I am able to use pid provider for this. But my application forks off children at times to handle requests. Is there a way I can stop the child process immediately after it is started so that I can attach a pid provider to that and trace the scanf calls in it? I have tried using the "create" probe but that did not help.

How accurate is "ustack"?
...if the time was really spent inside the next lower down level, wouldn''t that have been reflected in the ustack output? -- blu There are two rules in life: Rule 1- Don''t tell people everything you know ---------------------------------------------------------------------- Brian Utterback - Solaris RPE, Sun Microsystems, Inc.

Re: WLAN on dell 1501 with NDIS and Solaris 10 06/11
Did find a solution to this? I am getting the same relocation errors. It seems rather odd that the relocation errors should refer to the directory that ndis is built in, rather than the one it is installed in. That doesn''t make sense, does it?

monitoring tcp writes
i''m using the following probe to calculate how many bytes are being written by tcp write calls, by process and total: fbt:ip:tcp_output:entry { this->tcpout_size = msgdsize(args[1]); @tcpout_size[execname] = sum(this->tcpout_size); @tcpout_size["TOTAL_TCP_OUT"] = sum(this->tcpout_size); } I run this probe for N seconds. I suppose that if i get the
