John - I notice you had this issue a couple of years ago. Do you have any more experience with this problem now?

I had an app which I was close to completing. I ran my functional tests and the terminal window completely froze. Eventually I had to reboot.

After doing so I couldnt get the app to run again so I decided to take this oppourtunity to quickly rebuild the app. There were a couple of changes I wanted to make to the models, nothing major, just changing the max length of fields etc.

When I copied over the tests from the previous app to the new app and ran them I expected to see a few errors reflecting my changes but instead the whole app freezes. I can only run three or four tests at a time or I get this message:

ruby(3339) malloc: \*\*\* vm\_allocate(size=1069056) failed (error code=3) ruby(3339) malloc: \*\*\* error: can't allocate region ruby(3339) malloc: \*\*\* set a breakpoint in szone\_error to debug ruby(3339) malloc: \*\*\* vm\_allocate(size=1069056) failed (error code=3) ruby(3339) malloc: \*\*\* error: can't allocate region ruby(3339) malloc: \*\*\* set a breakpoint in szone\_error to debug ruby(3339) malloc: \*\*\* vm\_allocate(size=1069056) failed (error code=3) ruby(3339) malloc: \*\*\* error: can't allocate region ruby(3339) malloc: \*\*\* set a breakpoint in szone\_error to debug ruby(3339) malloc: \*\*\* vm\_allocate(size=1069056) failed (error code=3) ruby(3339) malloc: \*\*\* error: can't allocate region ruby(3339) malloc: \*\*\* set a breakpoint in szone\_error to debug [FATAL] failed to allocate memory rake aborted! Command failed with status (1): [/usr/local/bin/ruby -Ilib:test "/usr/local...]

Any ideas on where the problem could be?
