NoMemoryError when uploading large file

[cjwoodward@gmail.com]

Hi,

When I upload a large file I get the following issue:

NoMemoryError (failed to allocate memory):
/vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:193:in `quote'
/vendor/rails/activerecord/lib/active_record/query_cache.rb:72:in `send'
/vendor/rails/activerecord/lib/active_record/query_cache.rb:72:in `method_missing'

I am using ubuntu 9.04 but have had this issue on older version of ubuntu as well.

I am on a 256 mb slicehost account. Free -m outputs:

total used free shared buffers cached
Mem: 256 71 184 0 2 15
-/+ buffers/cache: 53 202
Swap: 511 60 451

I have changed my memory limits in both Server/Security and Server/Ruby to 256M.

Everything works fine if I start the application with mongrel and upload the file there.

If you have any ideas, please let me know?

Thanks,
Carl.
