Spotlight doesn't stop indexing

S.M.A.R.T.-status is checked.

Nothing noticable in the activity monitor.

I have 250 GB of disk space of which 30 GB are free.

I have 3 GB Ram.

The Console has some messages that are repeating; since the error is omnipotent I can't say which of them is the one that causes the error. If I filter by the string "SystemUIServer" I don't have any errors; one of the most noticable errors are

Jannis-iMac.local SIMBL Enabler for Sandboxed Apps[54380]: Set up watching for containers directory at URL file://localhost/Users/jannis/Library/Containers/

and

Jannis-iMac kernel[0]: 3862 ASYNC INCOMING TCP conStatus:0 flags:0 ->from:[some IP starting with 10.85.; changes with every error message]

I got Afloat installed which works as I know only with the windows of SIMBL-apps, but I don't use it's function very often and I tested that the error message has nothing to do with the using of some of Afloat's functions.

Both messages seem to have no pattern, sometimes they don't come up for ten minutes. The first one is repeating itself 1 or 2 times in a minute then, the second one 10 times in 5 seconds.

Last repeating thing are

Jannis-iMac kernel[0]: Sandbox: sandboxd(54443) deny mach-lookup com.apple.coresymbolicationd

and

Jannis-iMac.local sandboxd[54443] ([54442]): mdworker(54442) deny mach-lookup com.apple.ls.boxd

I got 6,24 GB of page outs (0 byte/s). If that's important, I have 13,06 GB of page ins too, and 4,36 GB used swaps.

For the diagnostic test: Should I also remove the 2 GB extra RAM I purchased for the Mac when I got it and always used? In fact, I think I never booted the iMac without it and never before had such a problem as far as I can remember.

FileVault is deactivated, I just cipher my Time Machine Backups. I'll run the test when I'm home again.

Uptime is 1 day 18 hours 49 minutes.

What do page ins, page outs and Swap used mean?

First of all, starting in Safe Mode somehow did solve my problem and in the same time it didn't. That's because in safe mode, you simple can't use Spotlight - or at least you don't find a single entry with it. That means Spotlight isn't indexing or calculating the time needed for it - but since spotlight seems to be shut off completely that doesn't mean anything. That also means I can't use the safe mode to find the problem.

Above that, I also have a problem with the time machine, it takes hours to make a backup (this -> https://discussions.apple.com/thread/4436120 thread) but that was solved somehow with the Safe Mode.

There is no StartupItems-folder or -file in /private/var/run/, in /Library/StartupItems there is EyeConnect, no files in /System/Library/StartupItems, 229 files in /System/Library/LaunchDaemons (shall I list them all here?) and 8 files in /Library/LaunchDaemons: at.obdev.littlesnitchd.plist, com.adobe.fpsaud.plist, com.freemacsoft.appcleanerd.plist, com.radiosilenceapp.nke.PrivateEye.plist, com.timesoftware.timemachineeditor.backup-auto.plist, com.timesoftware.timemachineeditor.helper.plist, org.freedesktop.dbus-system.plist (this file is an alias) and org.macosforge.xquartz.privileged_startx.plist.

I use Little Snitch, adobe is probably for the flash player, I use AppCleaner, time Machine Editor and xQuartz. I don't know what the other entries are, could someone explain? I'd delete them if they aren't needed by any program I use. I think i recognize PrivatEye as a program which I installed once and deleted shortly after that, so I can at least delete this, but what's freedesktop.dbus-system?

As 3rd party PreferencePanes I have DivX, Flash Player, Flip4Mac, MacFUSE (Tuxera), Perian and Secrets (which I just use to always show the tab bar in Safari).

Wow, thanks. Editing the two mdworker-files and emptying var/folders worked for me, booting much faster now. Now I have another problem: Spotlight switches between indexing (with the little dot in the icon) and not indexing, but not finding anything. There are some entries, but they are all irrelevant for me, they come from my external drive, music library or game folders - I can't see any pattern except all searchable entries are some sort of files, no programs. At first the terminal said the Spotlight Server was disabled, that isn't the case anymore, but the switching between indexing and not indexing keeps being existent and annoying. I'll sleep over it and look at it again tomorrow.

Spotlight is done, finds everything as far as I can see. Hopefully this is over now.

...okey, it is not over. Spotlight is in the same pattern as before, calculating the time for indexing without ever starting the actual index process. Any other ideas?

Did that already in my post with timecode 16.10.2012 08:35
