You have luck that a generous user has donated me a RPi B+ … with some
time, I am in a position to exactly reproduce what you encounter;-)
What system software are you using, a standard image?

Of course, consuming that much memory is not expected, but this depends
on what you are demanding. Could you go into more detail?

1. Are you working with the library or the mpg123 binary?
2. How many parallel instances?
3. How is this actually plumbed together? 130 files opened at once and
   ready for sampling?

Also, some profiling data would be nice. /usr/bin/time is a start, as
it also prints out memory usage (not shell-builtin time).


Alrighty then,

Thomas

PS: I wonder if you are trying to implement a sampler of some kind.
