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 the 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!

What does the copy source look like? Lots of files, NAS or what? –  jtreser Sep 14 '12 at 13:07
    
25Gb worth off of a NAS drive –  Touff Sep 16 '12 at 11:17

Long story short, it turned out to be a 4.3mb CSV file on my desktop that quicklook had issue with. Deleted it and everything went back to normal... Strange.

Thanks for sharing. How did you figure out it was this document? It may help others looking to resolve similar problems in the future. –  Justsomeguy Oct 10 '12 at 17:38
    
Having done numerous clean installs, I finally realised it only ever happened when I started copying my data from my NAS back onto my mac - 300GB worth. In order to find the culprit I thought I would only copy a folder I really needed which were a few documents I had, about 100mb worth. Its when I copied that folder I realised that my system was misbehaving and started copying each and every file one by one until I came across that particular CSV file. I have other CSV files but that specific one for some reason just didn't agree with my system. –  Touff Oct 10 '12 at 21:53
