It's part of the API of JACK... so any application can cause it to happen 
for any reason.  It usually doesn't happen automatically, but as the 
result of a user's interaction.

For example, the attached C++ program gives you a command-line tool to 
change the buffersize on the fly.  Compile & run it like this:

    $ g++ -o jack_set_buffer_size jack_set_buffer_size.cpp -ljack
    $ ./jack_set_buffer_size 1024

It's pretty simple to write a similar app. for samplerate.

HTH,
Gabriel
