Hi,all

my server. it  crashes  ,then can't works ,the version is
"2.7.1-0ubuntu4",OS ubuntu12.04_x64 .
when I run rabbitmqctl list_queues
the result is

error: ~p~n",["inet_tcp",eaddrinuse]}
{error_logger,{{2012,7,24},{13,37,49}},crash_report,[[{initial_call,{net_kernel,init,['Argument__1']}},{pid,<0.20.0>},{registered_name,[]},{error_info,{exit,{error,badarg},[{gen_server,init_it,6},{proc_lib,init_p_do_apply,3}]}},{ancestors,[net_sup,kernel_sup,<0.9.0>]},{messages,[]},{links,[<0.17.0>]},{dictionary,[{longnames,false}]},{trap_exit,true},{status,running},{heap_size,377},{stack_size,24},{reductions,376}],[]]}
