NoMemoryError

I am using the Openbase adapter and have had a similar glitch here
and there, but after I go into production I consistently get an error
on one page.

ActionView::TemplateError (NoMemoryError: failed to allocate memory:
SELECT * FROM …

I cannot track down the exact location of the error, but the
production log says it was around:
/usr/local/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/
active_record/connection_adapters/abstract_adapter.rb:120:in log' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/ active_record/connection_adapters/openbase_adapter.rb:152:inexecute’
/usr/local/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/
active_record/connection_adapters/openbase_adapter.rb:222:in `select’

The development WEBrick spits this out occasionally:
ruby(3306,0xa000ed98) malloc: *** error for object 0x219ab00: pointer
being reallocated was not allocated
ruby(3306,0xa000ed98) malloc: *** set a breakpoint in szone_error to

ruby(3306,0xa000ed98) malloc: *** error for object 0x219ab00: pointer

debug
/usr/local/lib/ruby/1.8/yaml.rb:380: [BUG] Bus Error
ruby 1.8.4 (2005-12-24) [powerpc-darwin8.4.0]

Are these ruby glitches or something in the Openbase connection? Any
tips on debugging this problem?

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

Command failed with status (1): [/usr/local/bin/ruby -Ilib:test

Any ideas on where the problem could be?

thanks
