[rabbitmq-discuss] rabbitmqctl status terminates all Web-STOMP client connections

[Adam Ashley]

We're using RabbitMQ 3.0.1 from the RabbitMQ supplied Debian packages to 
provide a link to a HTML based application. This takes advantage of the 
Web-STOMP plugin. Currently the client is making use of the iframe-xhr 
capabilities of the SockJS library when connecting.

Connections work successfully and will stay up for days at a time until 
"rabbitmqctl status" is run on the rabbitmq server. At that point all 
connections are terminated and due to the iframe-xhr in sockjs the client 
doesn't always see this disconnect.

When rabbitmqctl status is run the following appears within the log files:

=ERROR REPORT==== 18-Dec-2012::13:16:52 ===
** Generic server <0.1627.0> terminating 
** Last message in was which_children
** When Server state == {state,
                         {sockjs_session,
                          {<0.1624.0>,
                           [{peername,{{10,253,16,101},57724}},
                            {sockname,{{10,253,14,30},15674}},
                            {path,"/stomp/062/bv649208/xhr"},
                            {headers,
                             [{'Referer',
                               
"http://mq:15674/stomp/iframe.html?t=1355807743929"}]}]}},
                         <0.1626.0>,
                         {resume,#Fun<rabbit_stomp_frame.0.132048132>}}
** Reason for termination == 
** {{case_clause,{odd_request,which_children}},
    [{rabbit_ws_client,terminate,2},
     {gen_server,terminate,6},
     {proc_lib,init_p_do_apply,3}]}

And this is output at the console where the command was run:
root at mq01:~# rabbitmqctl status
Status of node rabbit at mq01 ...
Error: {{{case_clause,{odd_request,which_children}},
         [{rabbit_ws_client,terminate,2},
          {gen_server,terminate,6},
          {proc_lib,init_p_do_apply,3}]},
        {gen_server,call,[<4974.1627.0>,which_children,infinity]}}

This only occurs when a Web-STOMP client is connected. Normal STOMP clients 
do not have an issue.
