Hi,
we have some performance issues with our riak cluster, from time to time
we have a sudden drop in performance (already asked the list about this,
no-one had an idea though). Although not the same time but on the
problematic nodes we have a lot of these messages from time to time:

Can anyone explain to me what these messages mean and if I need to do
something about it? Could these messages be in any way related to the
performance issues?
