This has been driving me crazy: I have a file upload controller/view  
that finally uploads a file with this code in the controller:

File.open("#{filepath}/#{filename}", “wb”) do |f|  
f.write(@params[:document][:file].read)  
end

This works great for files large and small in webbrick and in on an  
Apache/FastCGI setup. However, on my production box which is running  
Lighttpd 1.4.7, this functionality fails about 50% of the time for  
files over 100 KB. When I say ‘fail’, I mean that the file just never  
appears in “#{filepath}/#{filename}”. The f.write command does not  
throw an error and no errors appear in log/production.log,  
log/fastcgi.crash.log or the lighttpd\_error.log. Very odd.

Is there some Lighttpd directive regarding upload file size I need to  
include in my .conf file? Some multipart chunk thing I need to know  
about? How should I go about getting to the bottom of this? (Please! I  
dread wrestling with FastCGI/Apache again.)

Your help/suggestions are greatly appreciated.

I have the same issue, after 100K I have problem. Anybody has any idea?  
I work with file\_column + imagemagick

Any answer on this?

For me the answer was to clear the cache I had stowed in  
lib/image\_upload\_cache, make sure permissions were correct everywhere,  
clearing all past ruby session files and restarting the server. I’m not  
sure where file\_column caches things, but I would try and find out and  
clear it out. HTH

Hi Henry,

I was hitting an upload limit of 4mb, which was solved on the latest  
lighty release, 1.4.8. Also, if you’re using Safari (I believe there  
some issues with IE/PC as well), it might be worth adding this to your  
lighttpd.conf:

$HTTP[“useragent”] =~ “^(._MSIE._)|(._AppleWebKit._)$” {  
server.max-keep-alive-requests = 0  
}

Safari would choke on uploads above 64K, there was a thread about this  
on textdrive i think

(not sure whether the keep-alive-requests was solved on 1.4.8, btw…  
might have)
