cffile upload

Currently running CF9 on Apache.  Trying to use cffile to upload files and store in an Oracle database as a blob.  Running into two different problems:

1. When trying to upload any document (e.g. Word, Excel, pdf) that is greater than approximately 128k, receiving what looks like an Apache error stating that the entity is too large.  Have researched to see what parameter is limiting this but can't find it.   CF Admin max post size is set to 5meg.

2. Am able to successfully upload and retrieve a Word/pdf document of approximately 63k or less, but anything larger does not throw an error but when retrieved and tried to open, a MS Word error is displayed stating that the file is corrupted.

Any assistance would be greatly appreciated.
