How large should a mogilefsd process become?

[Jay Buffington]

You could use GTop and monitor the memory usage before and after the
replicator does a task to determine where the leak is.

This example is for mod_perl, but you could apply it to mogile:
http://perl.apache.org/docs/1.0/guide/performance.html#Measuring_the_Memory_of_the_Process

This only happens when you insert large files?
