+++ This bug was initially created as a clone of Bug #1322609 +++

Starting with erlang-erts-R16B-03.10min.6.el7ost.x86_64, the log handler
repeatedly crashes and fills up the rabbitmq startup_log with entries like:

Event crashed log handler:
{info_msg,<0.1719.0>,
          {<0.1832.0>,"Mirrored ~s: Adding mirror on node ~p: ~p~n",
           ["queue 'l3_agent_fanout_0f6bc20f4c54484f9de482cd6d83a15a' in
vhost
'/'",
            &#39;rabbit(a)overcloud-controller-1&#39;,&lt;6192.10668.1&gt;]}}
function_clause

Meanwhile the rabbitmq log is empty.

Looks like a regression introduced in the "Enable error_logger depth fine
tuning" patch.

R16B-03.16.el7 is also affected.
