Hi Truong,

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

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.
