Random error capturing snapshot

[esetnik]

The problem

Every now and then I will get a failure from percy saying "RequestError: Error: write EPIPE". I don't know how to reproduce it or fix it. Only happens in ~1/10 builds.

cypress-1     | [percy:sdk] [percy] Could not take DOM snapshot "snapshot name redacted (5909143)" (6254ms)
cypress-1     | [percy:sdk] [percy] RequestError: Error: write EPIPE (0ms)

Environment

• Node version: v22.12.0
• @percy/cli version: 1.30.4
• Version of Percy SDK you’re using: 3.1.3
• If needed, a build or snapshot ID: 37984291
• OS version: linux docker
• Type of shell command-line [interface]: sh

Details

If necessary, describe the problem you have been experiencing in more detail.

Debug logs

If you are reporting a bug, always include logs! Give the "Debugging SDKs"
document a quick read for how to gather logs

Please do not trim or edit these logs, often times there are hints in the full
logs that help debug what is going on.

Code to reproduce issue

Given the nature of testing/environment bugs, it’s best to try and isolate the
issue in a reproducible repo. This will make it much easier for us to diagnose
and fix.

Hi @esetnik ,

Can you please check by setting the concurrency to 1 in percy.yml and gradually increasing it?

Currently, we're unsure why this is happening, and it's not reproducible on our end.

[esetnik]

I can confirm it is still happening with:

discovery:
  retry: true
  concurrency: 1

Also tried @percy/cli@v1.30.6 and able to reproduce with that version as well.

I found that this is a duplicate of #451

Hi @esetnik This type of error comes when resources are fully utilized.
Can you check your pods metrics where you are running tests and see CPU and memory usage during the percy test executions.
You can also create a support ticket and we will look into it more.

[esetnik]

I don't think we are facing resource utilization issues.

[prklm10]

@esetnik can you create a support ticket on percy.

@esetnik can you create a support ticket on percy.

Ok, i just did.
