Console Log Errors

Question

I'm getting some errors and warnings in my console system log that I don't quite understand - they have me a little concerned since things have been running a little bit strange on my system over the past few days:
Mar 19 12:23:59 localhost DirectoryService[11]: WARNING - dsTouch: file was asked to be opened </var/run/.DSRunningSP1>: (File exists)
Does anyone know what the dsTouch file is (or does)? I can't find the file in /var/run/ even though it says it exists.
I also get this message *all the time* after every restart:
Mar 19 12:24:00 <computer name> airportd[24]: Error: ACInterfaceGetPowerPreference() called with invalid interface
Mar 19 12:24:00 <computer name> airportd[24]: Error: Not an ACInterfaceRef (null)
Any ideas as to what this means? I think it is related to the AirPort but I don't use any AirPort devices at all.
And this one has just started a few days ago:
Mar 17 09:23:47 localhost kernel[0]: hi mem tramps at 0xffe00000

Mar 19 12:39:03 localhost kernel[0]: hi mem tramps at 0xffe00000
I wonder if anyone with some more technical knowledge than I have can explain some of this - hopefully, there is nothing seriously wrong. I'm not getting any crashes or panics but just some generally strange behavior on my iMac in the last few days. I ran YASU on March 17th around 9:25 AM and I reset the PRAM on March 18th around 3:20 PM.
Thanks for any help you can provide,
Gerard

Thanks baltwo,
I didn't get the .DSRunningSP1 warning today at all in any of the console messages - I've looked back in the console system log and see that I only had that message once. But speaking of users and groups, I did notice something strange and I don't know if this helps any or not. I checked the sharing and permissions on my System folder using Get Info and noticed a group called "wheel". What is that all about? It says that "wheel" has read only privileges to the System Folder whereas the user "system" has read & write privileges and "everyone" has read only privileges. I've never seen a "wheel" user before?
I checked the sharing and permissions on my home directory and there is no "wheel" user there but there is an "unknown" user with read only privileges and a user called "everyone" with read only privileges.
When I set up this new iMac in January, I transferred all the data from my old iMac G5 (which was running Mac OS X 10.4.11) using the Migration Assistant. Everything copied over just fine but I'm wondering if some files that shouldn't have been copied over, did get copied over and are interfering with things...
Also, you mention Directory Services as being what controls users and groups but that is only under Mac OS X 10.4.x. Under 10.5.6, all I can fine is Directory and Directory Utility (which I find royally confusing - I found Directory Services in Mac OS X 10.4.x much easier to use). Unless I'm missing something?
Thanks for your help,
