One thing to keep in mind is that MRI's garbage collector never returns
memory to the system, and doesn't do a very good job in general.  MRI has a
tendency towards unbounded heap growth over time, especially in long-running
processes.

You might try JRuby if you don't have too many dependencies on C
extensions.  It uses the advanced garbage collection available in the JVM.
