[rabbitmq-discuss] bql causing crash on startup

Thu May 20 23:12:45 BST 2010

I am having, what appears to be, the same issue as this:
 http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2010-April/006924.html

log messages (startup messages that all look normal, then):

broker running
Erlang has closed
{"Kernel pid terminated",application_controller,"{application_start_failure,rabbitmq_bql,{shutdown,{rabbitmq_bql,start,[normal,[]]}}}"}
Kernel pid terminated (application_controller)
({application_start_failure,rabbitmq_bql,{shutdown,{rabbitmq_bql,start,[normal,[]]}}})

in rabbit.log:
=INFO REPORT====
started TCP Listener on 0.0.0.0:5672

=INFO REPORT====
    application: rabbitmq_bql
    exited: {shutdown,{rabbitmq_bql,start,[normal,[]]}}
    type: permanent

rabbit-sasl has quite a bit of log info.

                  {shutdown,10000},
                  {child_type,worker}]

Note that if I remove just the rabbitmq-bql.ez plugin (leaving the
amqp_client.ez and rfc4627_jsonrpc.ez plugins) rabbitmq starts up just
fine. Only when I add the rabbitmq-bql.ez plugin does it crash on
startup.
