Re: What does "...riak_core_sysmon_handler:handle_event:85 monitor long_gc..." mean?
Hi Gal,
You are indeed right in thinking that this is not a show-stopper. It's
essentially a warning that GC took a long time. Take a look at hte erlang
docs for more info on the specifics of long_gc [1].
As far as preventing them, you have two options: use less memory, or
increase the memory settings in your app.config to a point where Riak
doesn't complain any more.
Hope that helps.
Mark
