clientid: SvrSub-8.148.245.36-5osojC的客户端自2026-06-17T08:59:40.513379+08:00连接上EMQX服务器并订阅主题topic: Device/publish/d/+/telemetry，链路和订阅一直正常，但持续至2026-06-17T19:07:51.181284+08:00时，订阅莫名其妙的被取消了（可以确定客户端未主动取消订阅），这是什么原因导致的？

zhongwencool · 2026 年6 月 18 日 10:43

你贴的日志里能看到：08:59:40 收到 SUBSCRIBE，SUBACK ReasonCodes=[1]，订阅建立成功；19:07:51 出现 emqx_trace:unsubscribe/2；后面同一个连接还在 PINGREQ/PINGRESP。关键缺口是 19:07:51 前后有没有 MQTT 协议层的 UNSUBSCRIBE 报文。
正常情况下，EMQX 不会给一个仍在线的普通客户端定时取消订阅：

grep 'SvrSub-8.148.245.36-5osojC' emqx.log \
  | egrep 'UNSUBSCRIBE|unsubscribe|client.disconnected|takenover|discarded|session|kick|terminate|SUBSCRIBE|SUBACK'

是否有 mqtt_packet_received ... UNSUBSCRIBE。有的话就是客户端库或业务代码发出来的，去查客户端订阅管理逻辑。
是否有同 Client ID 接管：takenover / discarded / 新的 CONNECT。同一个 Client ID 多实例会导致旧会话/订阅被清理。
是否有人或程序调了管理 API，例如 /clients/{clientid}/unsubscribe、踢下线、批量取消订阅。看 Dashboard 操作审计和 API 访问日志。
如果是集群，贴一下 19:06:30 到 19:08:30 这段完整 trace，别只截 unsubscribe 那一行。

如果完整 trace 里也没有 UNSUBSCRIBE 报文，也没有 API/踢下线/同 Client ID 接管证据，这个就可以按 EMQX 订阅状态异常来看，最好带版本号、部署方式和这段完整 trace 提 issue。

CHENJR · 2026 年6 月 18 日 13:06

提的4种情况都没有，就是莫名其妙的出现了取消订阅的日志，在Dashboard上也看不到该订阅内容了。如果是相同clientId接管，日志中会有记录；同样也没有调用管理API进行取消订阅；目前是单机部署。EMQX版本是5.4.0。

zhongwencool · 2026 年6 月 18 日 13:55

看起来像是 EMQX V5.4.0 的订阅状态异常。

已经排除了协议层 UNSUBSCRIBE、同 Client ID 接管、管理 API、集群。

现在想看看：订阅表真实状态，以及触发取消订阅前后的完整日志。

先在节点上直接看订阅表：

emqx ctl subscriptions show 'SvrSub-8.148.245.36-5osojC'
curl -u key:secret \
  'http://127.0.0.1:18083/api/v5/clients/SvrSub-8.148.245.36-5osojC/subscriptions'

再把同一个 Client ID 在 19:06:30 到 19:08:30 的 emqx.log 和 trace 都切出来，不要只截 emqx_trace:unsubscribe/2 那一行：

cid='SvrSub-8.148.245.36-5osojC'
grep "$cid" emqx.log \
  | egrep 'SUBSCRIBE|SUBACK|UNSUBSCRIBE|unsubscribe|subscribe|takenover|discarded|client.disconnected|terminate|session|kick|api'

emqx_trace:unsubscribe/2 不是 MQTT UNSUBSCRIBE 报文，它只说明 EMQX 内部把这个订阅移除了。如果完整日志里没有 mqtt_packet_received ... UNSUBSCRIBE，也没有 takeover、API、踢下线或断连，且连接后面还在正常 PINGREQ/PINGRESP，那就可以排除是客户端主动取消的了。

5.4.0 比较老，后续版本修过一批路由/订阅状态一致性问题。能升级的话，先升到 5.4 的最新补丁版本或更高版本再观察；如果暂时不能升，就带上上面两段证据提 issue。关键日志就是：连接仍在线、订阅从 subscriptions show 消失、没有协议层 UNSUBSCRIBE / 管理 API / takeover。

zhongwencool · 2026 年6 月 18 日 13:58

看了源码：在 v5.4.0 的版本里面能在 trace 里面打印 emqx_trace:unsubscribe/2的情况只有下面三种：

服务端管理接口/CLI 强制取消订阅
- REST/Dashboard：POST /api/v5/clients/:clientid/unsubscribe
- CLI：emqx ctl subscriptions del <ClientId> <Topic>
同 Client ID 会话接管
新连接使用相同 Client ID 接入时，旧 channel 在 takeover 结束阶段会对旧订阅执行 emqx_session_mem:takeover/1，里面会遍历订阅并调用 emqx_broker:unsubscribe/1。
这种情况通常会伴随 takenover、新的 CONNECT、旧连接断开；如果后面同一个 peername 还持续 PINGREQ/PINGRESP，这个可能性就直接可以排除了。
客户端真的发了 MQTT UNSUBSCRIBE

先把你贴出来的 API Key/Secret 撤销。curl -u ... 里的密钥已经发到公网了，别继续用这组 key。

这次日志更关键：不是单个 SvrSub-8.148.245.36-5osojC 异常。19:07:17、19:07:34、19:07:51 三个不同 Client ID 都出现了 emqx_trace:unsubscribe/2，而且后面还继续 PINGREQ/PINGRESP，这基本可以排除客户端断连、同 Client ID 接管、单个客户端库自己取消订阅。
现在更怀疑管理面操作：Dashboard / REST API / CLI 触发了 broker 侧取消订阅。你日志里 19:06:52 有一条：

msg: dashboard_login_successful ... username: <<"admin">>

它刚好在这些 unsubscribe 前一分钟。先查审计日志，不要只查 emqx.log：

grep -nE '19:06|19:07|unsubscribe|subscriptions|clients/.*/unsubscribe|dashboard|rest_api|api_key|jwt_token' /opt/emqx/log/audit.log*

如果审计日志没开，先开审计后复现一次，并把 ignore_high_frequency_request 临时设成 false：

log.audit {
  path = "./log/audit.log"
  ignore_high_frequency_request = false
}

同时在复现前后看两个计数：

emqx ctl broker metrics | egrep 'client.unsubscribe|packets.unsubscribe.received'

如果 packets.unsubscribe.received 没涨，但 client.unsubscribe 涨了，基本就是内部/管理面取消订阅，不是 MQTT 客户端发的 UNSUBSCRIBE。

还有一点：你后面查到 CLIENTID_NOT_FOUND，只能说明查询时这个客户端已经不在线了。它不能反推 19:07:51 那一刻客户端不在线；19:08:51、19:10:51 的 PING 日志已经说明当时连接还活着。
如果审计日志里也没有 Dashboard / REST API / CLI 记录，那这组证据就够明确是个 bug 了：EMQX 5.4.0 单机、多个在线连接在无 MQTT UNSUBSCRIBE 报文的情况下发生 broker.unsubscribe。
