Hi all,
In this post, I will explain the analysis of the issue when there is an alert showing all information about the vehicle but no photo.
Problem Description
White image occurred when checking Dynamic Lists in Face App.
Version Information:
Model: IVS3800
Version: C50SPC325

Problem Analysis
After checked with iClient devitool and iClient culog, and it was found that iClient could not get the image from IVS3800.

According to the iClient log, it was found that getting image requests failed.

From the above picture, iClient had sent out get image request but no image was returned by IVS3800.
Checked with VCMSDK log, it was found that this MP returned error after VCMSDK sent get image request. All intelligent-related services need to go through VCMSDK.

Based on the IP, it was found that the MP container is MP-0002.
According to the MP log, it was indicated that the mp process was abnormal since 6/23 because it could not connect to the database during the cluster communication failure period. So the mp process is stuck in this state.

Log printing stopped since 6/23 which indicated that the mp process was abnormal since then.

This log indicates that this MP container could not connect to the gauss database on 6/23.

Cluster communication failure occurred on 6/23
Root Cause
Based on the log, the mp process of MP-0002 was at a suspended state because it could not connect to the gauss database during the cluster communication failure period. Therefore, images in this MP container could not be sent to iClient.
The fault occurred a long time ago, and the information during the fault time is insufficient. Therefore, the specific cause cannot be determined.
Solution Description
Restarted mp process of MP-0002, then issue was restored
Thanks for reading!
