Hi,

In a cluster with 27 nodes, running 2.0.0, I upgraded one node to 2.1.1
(riak-2.1.1-1.el6.x86_64.rpm). Since them, this node is producing these
kind of logs, every couple of minutes:

2015-05-27 14:56:31.978 [info]
<0.94.0>@riak_core_sysmon_handler:handle_event:92 monitor long_schedule
<0.1201.0>
[{initial_call,{riak_core_vnode,init,1}},{almost_current_function,{gen,do_call,4}},{message_queue_len,1}]
[{timeout,1329},{in,{gen,do_call,4}},{out,{gen,do_call,4}}]


Any idea what this is and if it's harmful? I'd like to double check
before upgrading the other nodes

Thanks
dams.
