No, those messages simply mean that the process had a single garbage
collection event that took 57 milliseconds.  If you're doing a lot of
work on a lot of data, then the default settings in the etc/app.config
file may be too low.  Edit the riak_sysmon section of that file and
revise the ceilings upward appropriately, particularly the gs_ms_limit
item, since that's the one that you might be seeing excessive
notifications.  You may also want to change the heap_word_limit item,
