Logging out and in on OS X takes 4-5 minutes?

I've got a 3.4 GHz i7 iMac (8 cores) with 24 GB of RAM. (2 16 GB chips plus 2 4 GB chips.) I know this amount of RAM is "officially unsupported" which is why I mention it.

Lately logging out (to restart into boot camp) takes 4 or 5 minutes, and logging back in does as well. When logging out, the Finder disappears and it goes to the gray screen that you see just before it restarts... but then sits there for 4-5 minutes. When logging in, you see the "enter user name / password" screen with the spinning progress indicator... which again takes 4-5 minutes.

Is it copying all 24GB of RAM to disk, and restoring it, to re-open windows in saved states or something like that? If not what? I reboot into boot camp fairly often for work and this is ridiculous.

Posting console log from when I think I logged in this morning:

Since I'm limited in how much I can post, I edited out a lot of acvpnagent entries such as this one:

6/4/13 11:20:00.007 AM acvpnagent[62]: Function: if_get_interfaces File: Utility/if_unix.cpp Line: 186 Invoked Function: ioctl Return Code: -1 (0xFFFFFFFF) Description: unknown (SIOCGIFDSTADDR) for interface "utun0"

I think this is related to some stuff work installed on my machine before I got it, but there are lots of these messages prior to attempting to log in, so I think they're unrelated.

UPDATE 1:

I tried the solution proposed here:

http://www.techsmog.com/index.php/2011/02/23/fixing-the-slow-loginlogoutauthentication-issue-in-osx-snow-leopard/

but this did not help.

Solution 1:

Okay, found the solution. Not sure which of these did the trick as I did both at once:

1) Shut down computer, unplug power cord and wait 15 seconds. Plug cord back in and wait 5 seconds, then turn on.

2) Immediately after turning on (before gray screen appears but after chime) hold down Command-Option-P-R all at once to zap PRAM. Keep holding until computer restart.

Now shutting down takes only 30 seconds, and logging in takes only 15. Soooooo much better!
