Erlang error while stopping couchbase service on a node - ops/sec hits 0

Version: 3.0.0 enterprise edition (build-913) Ubuntu 12 x64 - 4 nodes with 2 cores and 14GB memory per node. behavior: error while stopping service under load (6K set ops/sec). Caused 10 seconds of 0 sets/sec even though this is 1 out of 4 nodes. expected behavior: no error and no outage on ops/sec on other nodes. azureuser@cbase-32 :~$ sudo service couchbase-server stop {error_logger,{{2014,7,18},{15,49,20}},"Protocol: ~tp: the name executioner@executioner seems to be in use by another Erlang node",["inet_tcp"]} {error_logger,{{2014,7,18},{15,49,20}},crash_report,[[{initial_call,{net_kernel,init,['Argument__1']}},{pid,<0.21.0>},{registered_name,[]},{error_info,{exit,{error,badarg},[{gen_server,init_it,6,[{file,"gen_server.erl"},{line,320}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,239}]}]}},{ancestors,[net_sup,kernel_sup,<0.10.0>]},{messages,[]},{links,[#Port<0.53>,<0.18.0>]},{dictionary,[{longnames,true}]},{trap_exit,true},{status,running},{heap_size,610},{stack_size,27},{reductions,771}],[]]} {error_logger,{{2014,7,18},{15,49,20}},supervisor_report,[{supervisor,{local,net_sup}},{errorContext,start_error},{reason,{'EXIT',nodistribution}},{offender,[{pid,undefined},{name,net_kernel},{mfargs,{net_kernel,start_link,[[' executioner@executioner ',longnames]]}},{restart_type,permanent},{shutdown,2000},{child_type,worker}]}]} {error_logger,{{2014,7,18},{15,49,20}},supervisor_report,[{supervisor,{local,kernel_sup}},{errorContext,start_error},{reason,{shutdown,{failed_to_start_child,net_kernel,{'EXIT',nodistribution}}}},{offender,[{pid,undefined},{name,net_sup},{mfargs,{erl_distribution,start_link,[]}},{restart_type,permanent},{shutdown,infinity},{child_type,supervisor}]}]} {error_logger,{{2014,7,18},{15,49,20}},crash_report,[[{initial_call,{application_master,init,['Argument__1','Argument__2','Argument__3','Argument__4']}},{pid,<0.9.0>},{registered_name,[]},{error_info,{exit,{{shutdown,{failed_to_start_child,net_sup,{shutdown,{failed_to_start_child,net_kernel,{'EXIT',nodistribution}}}}},{kernel,start,[normal,[]]}},[{application_master,init,4,[{file,"application_master.erl"},{line,133}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,239}]}]}},{ancestors,[<0.8.0>]},{messages,[{'EXIT',<0.10.0>,normal}]},{links,[<0.8.0>,<0.7.0>]},{dictionary,[]},{trap_exit,true},{status,running},{heap_size,376},{stack_size,27},{reductions,117}],[]]} {error_logger,{{2014,7,18},{15,49,20}},std_info,[{application,kernel},{exited,{{shutdown,{failed_to_start_child,net_sup,{shutdown,{failed_to_start_child,net_kernel,{'EXIT',nodistribution}}}}},{kernel,start,[normal,[]]}}},{type,permanent}]} {"Kernel pid terminated",application_controller,"{application_start_failure,kernel,{{shutdown,{failed_to_start_child,net_sup,{shutdown,{failed_to_start_child,net_kernel,{'EXIT',nodistribution}}}}},{kernel,start,[normal,[]]}}}"} Crash dump was written to: erl_crash.dump.1405698560.34968.babysitter Kernel pid terminated (application_controller) ({application_start_failure,kernel,{{shutdown,{failed_to_start_child,net_sup,{shutdown,{failed_to_start_child,net_kernel,{'EXIT',nodistribution}}}}},{k  * Failed to stop couchbase-server azureuser@cbase-32 :~$ sudo service couchbase-server stop  * Failed to stop couchbase-server cbcollect_info output: https://s3.amazonaws.com/bugdb/jira/MB-11756/
