I am seeing a small Rails app freeze up after being up for a while. It  
appears  
to be unrelated to usage, but to happen after about a months’ or more  
time.

In my experience, they can die after a period of time. I usually use  
something like lighttpd/fastcgi instead because it will keep a pool of  
rubies on stand-by, and clean them up as they die off.

Unless you’re on somes broken OS or version of Ruby or an ancient  
Mongrel version, it’s more than likely the application’s fault.

We still have production Mongrel processes that have been running for  
over a year in some places and serving regular traffic.
