crashed: too many corpses being created

The following didn't work for me, but creating/fixing the file rc.server has worked for many others with a similar problem. To do this, boot up your Mac in Single User mode (hold Cmd+S immediately as you hear the Apple chime).

Once the initial verbose script has finished loading, enter the following two lines:

mount -uw /

/usr/bin/nano /etc/rc.server

The first line allows your Mac's system files to be written to. The second line opens/creates rc.server as a file, using the nano process. Once the file opens, delete any script that already exists (don't worry if it's empty) and then enter the following two lines:

#!/bin/sh

/usr/sbin/BootCacheControl jettison

Once finished, save your changes with Ctrl+O and then exit nano with Ctrl+X. Your Mac may then automatically reboot, but if it returns you to Single User mode, enter the following line:

reboot

Hope this works for you!

Note: if you're using a UK-type keyboard like myself, you might have a hard time creating the # hash symbol required for the rc.server script. UK input requires Alt+3 to create #, but Alt seems to have no effect within Single User mode. To get around this, I used Recovery Mode (boot up and hold Cmd+R) and changed my input to a US keyboard, then rebooted. US input uses Shift+3 to get #, which works fine in Single User mode
