weird behavior multipart form uploads

[krafer]

Using:
* Mac OSX 10.4.10
* LiteSpeed 3.0.2 Standard
* Rails 1.2.3

I have a page with a single multipart form, which takes a file input to upload text files. About 50% of the time after selecting a file and clicking submit litespeed seems to just hang and I have to hit submit again to get the file to upload. Nothing even shows up on the rails logs when this occurs, but in the litespeed error logs I get this:

2007-08-18 01:57:59.794 [NOTICE] [127.0.0.1:55587-0#localhost] Premature end of response header.
2007-08-18 02:11:07.014 [NOTICE] [Rails:localhost:/] stop worker processes

Looks like your application may write some debug message to stdout before the response header was sent.
