And lots more.
People havent fount a real reason for it.
Seen it on some other fora too.
Happens in both Lion, and Lion Server
Anyone ?
Mac Pro, Mac OS X (10.7), Server
I had the same issue and I tracked it down to a call I had in a script to localhost. I changes localhost to the machines ip address and no longer get the messages
Hi, what did you do to solve the problem?
"changed the localhost to the machines ip address" ?
I don't get it:-(
Can you explain what you exactly did?
Thanks!
It was caused by my script (I had a call to localhost).
What does Console report? Can you post the complete line for the error you're getting?
11.08.11 19:14:43,000 kernel: nstat_lookup_entry failed: 2
well this is what happend in the Console!
I already tryed to fix the /etc/hosts
"localhost = 127.0.0.1 "
But it didn't help....I am still getting this Error nstat_lookup_entry!
An got it on a Lion Server and a Lion Client....and my Client can not reach with a ping another Computer in the network!
I had this same problem when I upgraded to Lion, and spent some time tracking down its source. I am running Easy Connect 1.8 to support screen sharing and file sharing with my iPad. When I killed Easy Connect, the error messages stopped.
If you are not running Easy Connect, and you see the problem. Try running Activity Monitor and look for any network based software that you have installed that is running in the background. Watch the kernel logs, and see if you kill the process, the messages stop. Then send a bug report into the application developer.
It also might be that server admin is causing trouble.
After a lot of searching I found there are serveral reasons for the messages.
Sinds yesterday I did NOT get ANY of these messages, until I started Server Admin.
First,
If you upgraded, check your file sharing.
To be shore, disable all filesharing that you may or may not have issued in the previous version.
Monitor the log while doing that, in my case the messages decreased to 0.
Second, find out if you have any 3d party software making connections OR monitoring connections.
Find out by using netstat what connections are in use.. do this thourowly !!
Then if your nstat messages went away, try different applications while monitoring the logs
This is the only way I could think of to narrow it down...
Now I am trying to figure out why SA is giving me these errors again...
You can test this with the following:
nc -z localhost 20-30
will work, and report open ports (the -z flag tells nc to report open ports, rather than initiate a connection.)
however, Console reports: 08/15/11 7:31:56.000 PM kernel: nstat_lookup_entry failed: 2
Looks like a Lion bug
This message stems from a new feature introduced in OS X Lion's kernel, which appears to collect network statistics. Given that every machine spits it out every now and then, it can safely be classified as simple noise.
The fact that it appears in the kernel log is probably a mere oversight on the side of Apple, as the message is certainly not critical and of absolutely no value. It looks like a debugging message the developer forgot to comment out.
This page by Simon Heimlicher analyzes the kernel source code and provides a kernel configuration change to disable network statistics collection and suppress the error message permanently.
Thanks dskilken, I had the same problem, and by Quiting EasyConnect, the error log stopped!.
And... another bug Nstat Lookup failure
