nstat_lookup_entry failed errors when running Mail

Not sure if this was happening prior to the upgrade to Lion, but now, every 30 seconds when I am running mail, I see the following:

7/21/11 7:36:08.000 AM kernel: nstat_lookup_entry failed: 2

7/21/11 7:36:38.000 AM kernel: nstat_lookup_entry failed: 2

7/21/11 7:37:08.000 AM kernel: nstat_lookup_entry failed: 2

7/21/11 7:37:38.000 AM kernel: nstat_lookup_entry failed: 2

I am not sure it is causing any problems, but seems to go away when I am not running mail. Any ideas what this could be?

I am also seeing this. It coincides with a dialog box flashing on the screen too quickly to see what it is.

I've done several clean installs and upgrades of server (attempting a good, solid install. Watching console like a hawk to see where I might screw up) and they're all doing this. I'd love to know what's going on. I don't see a dalog box though. Has anyone tried quitting everything but console and seeing if it still happens?

I tried to enable profile signing for device management, and increased the rate at which these happen exponentially. Just some additional info

I get about 30+ of those a day, with mail running all the time. It can't be anything to worry about, could it? I've noticed a lot less messages in the console now then with SL, even at 10.6.8...so things have improved, if using the console as a barometer is a valid measure.

Same problem after clean install of Lion (not on top of Snow Leopard)

Same here, I get it at the boot time. What bothers me the most is that it takes 7-15 seconds to show up, slowing down the boot strap together with other things, like the yukon2 ethernet driver just before of it. Maybe they are related.

For me this issue was solved by going into Login Options for my User Account (Sys Prefs / Users & Groups) and deleting the Network Account Server info (it had remembered my work's Exchange Server from an old email account). After I deleted that server, the errors went completely away.

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.
