</div>

when uploading a large file (8meg) to my live deployed railsapp website  
( [www.lifehoo.com](http://www.lifehoo.com) ) hosted on textdrive, it crashes the railsapp.

Is there a way in rubyrails to prevent this from happening?

Hi Truong,

Please paste your exception details, it is very hard to guess (maybe  
Zed S. can do some telepathic assistance, i heard he can do anything  
regarding rails 🙂 )

Hi, production.log and fastcgi.crash.log doesn’t show anything.

however, while logging in via ssh shell, I noticed this:

RMagick: Memory allocation failed `Cannot allocate memory’.

Any suggestions?

Thanks!

My best guess would be to add some more RAM to the machine. Or in some  
other way make more memory available to the process.

The problem with shared hosts is that your memory is limited. As soon  
as you go over a certain treshold, it just terminates your processes.  
I’m having similar problems with uploads and even downloads via  
send\_file on a2hosting’s servers. The shell also reads: out of  
memory, my processes are all killed (including mongrel, the site goes  
offline) and a core file is dumped. The same application runs without  
a problem on our VPS or dedicated server.
