I recently installed an SSD (m4 crucial latest firmware) with TRIM enabled on my late 2011 MBP 13".

I did a clean install of Mountain Lion 10.8.1, enabled FileVault 2 and everything was working fine for about 2 weeks until Finder just started randomly killing itself every time I mounted a DMG or just launched some random app.
At the time I was getting this error:

com.apple.quicklook.satellite[205]: [QL] Using too much memory (308 MB), hit critical threshold (120 MB), exiting immediately to clean up.

Backed up all my files manually and did another clean install.
Installed a few applications, re-enabled FileVault, waited 2 days, everything was running fine.
Decided it was time to copy my files back over.
Whilst copying over Ethernet with Wifi enabled, I disabled the wifi, Finder hangs had to hard reset.
On reboot - error was back:

I cannot find anything similar on Google and for the life of me cannot figure out what is wrong.
It's giving me the same error on every reboot and every 3-7 minutes. It's only matter of time I suspect before Finder starts going nuts. It's also worth mentioning that very few applications are installed at the moment.

Any help would be greatly appreciated!

Have you tried qlmanage -r or moving Quick Look plugins out of ~/Library/QuickLook/ and /Library/QuickLook/? –  ؘؘؘؘ Sep 13 '12 at 13:27
    
Thanks for that Lri, unfortunately that hasn't solved it :S I checked the paths you mentioned but the QuickLook folder isn't present in ~/Library only in /Library –  Touff Sep 14 '12 at 0:28

After a lot of trial and error, the problem turned out to be quite a large CSV file that had been created on an old version of excel that quicklook constantly attempted to generate a preview for. Strange indeed.
