crashed: too many corpses being created

After installing a Yosemite update on my laptop, when it boots, it seems to all be fine until about the loading bar is maybe 2/3 done, then slows to a crawl and takes another 20 minutes or so to reach full - where it stays. I have no cursor or anything else during this time, but my caps lock button light will go on an off when I press it.

I've tried:
-Resetting PRAM/NVRAM
-Booting into recovery mode and repairing the drive/partition. This seemed to be done successfully.
-Booting hardware diagnostics and doing a check. It says everything is fine.
-Safe boot. Takes the same length of time and hangs at the same place, so honestly not sure if I'm even doing it right.
-Verbose mode says every single process has crashed, with 'too many corpses being created.'. (picture - note that it's not actually blurry, just scrolling pretty fast so a photo wasn't the best)

It's a Mid-2011 15" Macbook pro, 2.2GHz with a 750GB hard drive and 16GB of RAM. I'm still doing a few other checks (currently re-installing 10.10 using a thumb drive to see if that fixes it), but has anyone got any ideas or had a similar problem?

MacBook Pro (15-inch Early 2011), OS X Yosemite (10.10.3)

So, here is the latest solution from Apple:

Restart your Mac and hold down Command-R tostart up from macOS Recovery.
If the startup drive has FileVault turned on, open Disk Utility and proceed with the next step. If FileVault is off, skip to step 5.
Select the startup drive and click Mount in the Disk Utility toolbar. When prompted, select a login name and enter the password. Then click Unlock to mount the startup drive.
Quit Disk Utility.
Choose Utilities > Terminal from the menu bar.
Type this command in Terminal:cd /Volumes/Macintosh\ HD/var/db/caches/opendirectory/
Modify the command to reflect the name of the startup volume if it's not Macintosh HD. Remember to use an escape character \ before each white space in the command path.
Press Return.
Type this command in Terminal:mv ./mbr_cache ./mbr_cache-old
The mv Terminal command is safer than the rm command. Errant white space in an rm command can destroy the user's data.
Press Return.
Quit Terminal.
Choose Apple () menu > Restart.

The first startup after running these commands takes longer than usual as the cache is recreated. Subsequent startups will take the normal amount of time.

Hope this will help you 🙂
