Azure-pipelines-tasks: Assertion failure in ROCKRemoteProxy (Xcode Build Task, Hosted Agent, MacOS)

Created on 14 Nov 2018 · 14Comments · Source: microsoft/azure-pipelines-tasks

When running a Xcode build on Hosted Agent (macOS) I get this error on 1 in a 10 builds. I do not know where it originates (not in our code). The error output is after the Xcode build is done (succeeded).

Not sure if this is the right place to report this.

Anyone know anything about this and have seen it?

I'm also seeing this in ~1/10 builds using Fastlane and TeamCity with Xcode 10

I am getting the same error on Azure Devops Pipelines, but while running snapshot/capture_ios_screenshots of fastlane as a script:

We started seeing this randomly on some travis builds after switching from Xcode 10 to Xcode 10.1

Also seeing this consistently on TravisCI only on Xcode 10.1
Anyone managed to solve it? Or at least understand where/why it originates?

I have researched this a lot and have not gotten anywhere so far.

This is what I found out so far:

I have identified is that this probably originates from a framework from Apple.
I have not found any information or reports at Apples dev forums yet.
It started when moving from Xcode 10 to Xcode 10.1 (as @paulb777 reported)
The frequency of the error is periodically increasing (not sure why).
I found this repo in the hunt: https://github.com/w0lfschild/macOS_headers/tree/master/macOS/PrivateFrameworks/ROCKit

This also happens in builds with Xcode 9.4.1.

chlandsi on 15 Jan 2019

Same problem here. Xcode 10.1

We're also seeing this error on the hosted mac pool at the end of our unit tests. I can't give a guess at the frequency, but 1 in 10 seems reasonable.

Same happens running Fastlane with Bitrise

Alex-Alex77 on 14 Mar 2019

We're seeing the issue running a plain xcodebuild command on TravisCI. Only when ACTION=test on iOS 12.1 for a framework target.

This is clearly not specific to Azure Pipelines, so closing this issue. The thread has a lot of useful details, thanks to all for sharing. We are not changing anything in Azure Pipelines or the Hosted macOS VMs yet but will be reviewing any workarounds we can provide to mitigate this issue.

FYI, we are experiencing the same problem in my team and the only solution we found was to have some logic that would retry the command when this particular problem is detected.
