Subject: [BUG] Intermittent Error Log and Online Message Delivery Issues with Additional Logs

Hello Team,

I hope this message finds you well. I'm writing to report a bug that I've encountered with the Open-IM-Server project. This issue is intermittent and seems to resolve itself after multiple restarts and tests. However, I haven't been able to identify the specific conditions that trigger it. I've included additional logs that may help in diagnosing the problem.

Error Log Details:

2024-10-12 15:40:36.538 ERROR   [PID:2740202]   openim-msggateway               [version:3.8.0]         [msggateway/online.go:91]                               update user online status                               {"operationID": "p_2740202_64", "error": "14 last resolver error: produced zero addresses"}

Additional Logs:

2024-10-12 15:40:36.538 DEBUG   [PID:2740202]   openim-msggateway               [version:3.8.0]         [mw/rpc_client_interceptor.go:44]                       RPC Client Request - setUserOnlineStatus                {"operationID": "p_2740202_64", "funcName": "/openim.user.user/setUserOnlineStatus", "req": "status:{userID:\"10004\" offline:2}", "conn target": "openim:///user"}
2024-10-12 15:40:36.538 ERROR   [PID:2740202]   openim-msggateway               [version:3.8.0]         [mw/rpc_client_interceptor.go:50]                       RPC Client Response Error - setUserOnlineStatus         {"operationID": "p_2740202_64", "funcName": "/openim.user.user/setUserOnlineStatus", "error": "rpc error: code = Unavailable desc = last resolver error: produced zero addresses"}

Additional Observed Behavior:

• Users are unable to receive online messages, indicating a potential issue with message delivery.

Environment:

• Operating System: Linux ubuntu 4.15.0-213-generic #224-Ubuntu SMP Mon Jun 19 13:30:12 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
• Open-IM-Server Version: Fork develop branch base on v3.8.0
• Discovery Service: ZooKeeper

Configuration File (config/discovery.yml):

enable: "zookeeper"
etcd:
  rootDirectory: openim
  address: [ localhost:12379 ]
  username: ''
  password: ''

zookeeper:
  schema: openim
  address: [ localhost:12181 ]
  username: ''
  password: ''

Observations:

• The error log appears sporadically without any discernible pattern.
• The issue seems to resolve itself after multiple restarts and tests, but the root cause remains unknown.
• Users are unable to receive online messages, which may be related to the error log.
• The additional logs indicate an RPC client request failure with the error "last resolver error: produced zero addresses".

Expected Behavior:

• The application should run without generating any error logs.
• Users should be able to receive online messages without any issues.

Additional Information:

• I've tried to replicate the issue multiple times but with no success in creating a consistent scenario.
• The error log does not seem to affect the functionality of the application immediately, but it's concerning as it may indicate underlying issues.
• I've attached a screenshot of the error log for your reference.

Additional Information from ZooKeeper:
Upon inspecting the ZooKeeper instances for user information when the issue occurred, everything appeared to be in order. Here are the details from the ZooKeeper inspection:

[zk: localhost:2181(CONNECTED) 1] ls /
[openim, zookeeper]

[zk: localhost:2181(CONNECTED) 2] ls /openim
[auth, conversation, friend, group, messageGateway, msg, push, third, user]

172.16.128.207:10110

The ZooKeeper nodes and their corresponding values were retrieved successfully, and no anomalies were detected in the user-related data. However, the presence of the error log and the inability of users to receive online messages suggest that there might be an issue with the service's interaction with ZooKeeper or other underlying components.

I would appreciate any guidance on how to proceed or what additional information you need from me to help resolve this issue.

Thank you for your attention to this matter. I look forward to your response.

Best regards,
Libo

There's an issue with "zookeeper," and we've removed it.
