Enhanced Smart Tags Training Workflow - Broken Pipe

[#1]

Hi Devs,

I am getting a Broken pipe exception while invoking the Enhanced Smart Tags training workflow from my local 6.5 author instance. The smart tags workflow is working fine, however it is always throwing a broken pipe exception on my error logs whenever I invoke a training workflow..

The similarity search JMX configuration is all passed while invoking validateConfigs. Any thoughts why the socket/pipe is getting closed prematurely. Is it the organisation network that causes this issue.

Caused by: java.io.IOException: Broken pipe

Most likely the certificate is incorrect or corrupted. From CRXDe delete /home/users/system/dam/dam-update-service/keystore

When it's completed re-do the entire Smart Tags configuration.

No luck again. I tried deleting the key store and performed the steps again.

If I am not wrong, we use a single certificate for smart tags endpoint & training endpoint. If it's a certificate issue, why the smart tagging works without any problem

How many images are you sending for a Smart Tags training? Is it very large in size batch of images? Can you try to reduce image size?

[#5]

I tried with multiple scenarios. By invoking on a folder with one image which is around 100KB. Also on a folder with 20-25 images similar sized images all images less than 250Kb

However the log says the below information as well.

03.12.2019 10:10:08.307 *INFO* [JobHandler: /var/workflow/instances/server0/2019-12-03_1/smart-tags-training_232:/content/dam/smart-tags/time] com.day.cq.dam.similaritysearch.internal.impl.TransferTrainingDataServiceImpl Successfully Completed Training Data Transfer for [/content/dam/smart-tags/time]

On subsequent run,

03.12.2019 12:39:32.665 *INFO* [JobHandler: /var/workflow/instances/server0/2019-12-03_1/smart-tags-training_233:/content/dam/smart-tags/time] com.day.cq.dam.similaritysearch.internal.impl.TransferTrainingDataServiceImpl Completed Training Data Transfer for [/content/dam/smart-tags/time]. No tags were transferred

But my smart tag training report is empty and the broken type issue is still there.
