[rabbitmq-discuss] Mgmt API stopped reporting a lot of stuff

[carlhoerberg]

So tiger03 was the node that had the stats db, which crashed, it couldn't be
restarted gracefully either, so did a "kill -9". The stats db moved to
tiger01, so everything works fine there now, but tiger02 reports: 

=ERROR REPORT==== 18-Apr-2013::23:14:56 ===
webmachine error: path="/api/overview"
{error,{error,{badmatch,false},
              [{rabbit_mgmt_wm_overview,version,1},
               {rabbit_mgmt_wm_overview,to_json,2},
               {webmachine_resource,resource_call,3},
               {webmachine_resource,do,3},
               {webmachine_decision_core,resource_call,1},
               {webmachine_decision_core,decision,1},
               {webmachine_decision_core,handle_request,2},
               {rabbit_webmachine,'-makeloop/1-fun-0-',2}]}}

When tiger03 started again the log contains a lot of these:

        {gen_server2,handle_msg,2},

and it stopped at "starting adding mirrors to queues                                    
...", but most notably, the whole cluster stopped deliver any messages!

The sasl log for tiger03 also contains:
