使用过程中发现backkends会无故丢失

[kingStart]

在使用过程中发现管理端会无故自动终止，导致无法找到backend

具体日志如下： 2018-11-22 14:17:57: (critical) proxy-plugin.c.1450: I have no server backend, closing connection 2018-11-22 14:17:57: (critical) network-mysqld.c.1387: plugin_call(CON_STATE_READ_QUERY) failed 2018-11-22 14:17:57: (critical) proxy-plugin.c.1450: I have no server backend, closing connection 2018-11-22 14:17:57: (critical) network-mysqld.c.1387: plugin_call(CON_STATE_READ_QUERY) failed 2018-11-22 14:17:57: (critical) proxy-plugin.c.1450: I have no server backend, closing connection 2018-11-22 14:17:57: (critical) network-mysqld.c.1387: plugin_call(CON_STATE_READ_QUERY) failed 2018-11-22 15:02:14: (warning) (libevent) event_del: event has no event_base set. 2018-11-22 15:02:14: (warning) last message repeated 101 times 2018-11-22 15:02:14: (warning) (libevent) event_del: event has no event_base set. 2018-11-22 15:02:14: (warning) last message repeated 101 times 2018-11-22 15:02:14: (warning) (libevent) event_del: event has no event_base set.
