[rabbitmq-discuss] RabbitMQ Causing Segmentation Fault on FreeBSD

[Brandon Munroe]

Yep, the VM is segfaulting (it exits with the message "Segmentation fault
(core dumped)").

The message in the logs reads:

** Generic server rabbit_mgmt_external_stats terminating
** Last message in was emit_update
** When Server state == {state,707130}
** Reason for termination ==
** {function_clause,[{lists,nth,[1,[]],[{file,"lists.erl"},{line,168}]},

{rabbit_mgmt_external_stats,'-get_used_fd/1-fun-1-',2,[]},
                     {lists,'-filter/2-lc$^0/1-0-',2,
                            [{file,"lists.erl"},{line,1271}]},
                     {lists,'-filter/2-lc$^0/1-0-',2,
                            [{file,"lists.erl"},{line,1271}]},
                     {rabbit_mgmt_external_stats,get_used_fd,1,[]},

{rabbit_mgmt_external_stats,'-infos/2-lc$^0/1-0-',2,[]},

{rabbit_mgmt_external_stats,'-infos/2-lc$^0/1-0-',2,[]},
                     {rabbit_mgmt_external_stats,emit_update,1,[]}]}

The only message on stdout/stderr is the one above.  We're running RabbitMQ
3.2.4 on Erlang R16B03-1, with HiPE compiled in (though we didn't specify
hipe_compile in the RabbitMQ configuration).
