⏱️ Build Failed: Timeout

conn read: read tcp 127.0.0.1:55578->127.0.0.1:39933: i/o timeout

Build Details

Category	Details
Build System	melange
Failure Point	QEMU VM communication during build environment setup

Root Cause Analysis 🔍

Network I/O timeout occurred while establishing or maintaining SSH connection to the QEMU virtual machine used for the build process. This indicates the VM became unresponsive or network connectivity was lost during the build environment initialization phase.

Analysis

Looking at the similar fixed build failures, I notice several patterns: 1) Version updates and dependency changes (Fix #0 updated PHP PECL package version and added pcre2-dev dependency), 2) Creation of new FIPS-compliant packages (Fix #1 created entirely new jaeger FIPS packages), and 3) Test framework standardization (Fix #2 replaced custom test commands with standardized test/tw framework). The common thread across all fixes is that they addressed infrastructure and dependency issues that could cause VM communication timeouts by ensuring proper dependencies, updating to stable versions, or using more reliable testing frameworks.

Click to expand fix explanation

Explanation

The suggested changes address the root cause of QEMU VM communication timeouts by: 1) Adding pkg-config dependency ensures proper library detection during the build process, preventing build failures that could cause VM hangs, 2) Reducing resource allocation from 30 CPU/20Gi to 16 CPU/16Gi prevents VM resource exhaustion which is a common cause of communication timeouts, 3) Adding dependency verification ensures all required libraries are properly linked before the main build starts, preventing mid-build failures that could leave the VM in an unresponsive state, and 4) Replacing custom test commands with the standardized test/tw framework improves test reliability and reduces the chance of test-related VM communication issues. These changes follow the patterns observed in the similar fixes, particularly the standardization approach from Fix #2 and the dependency management approach from Fix #0.

Alternative Approaches

• Add explicit timeout configurations in the pipeline steps to prevent indefinite waits that could cause VM communication issues
• Split the large Rust build into smaller chunks to reduce memory pressure and prevent VM resource exhaustion
• Add retry mechanisms for network-dependent operations like cargo operations that might fail due to intermittent connectivity
• Consider using a different Rust build approach such as cargo-c instead of cargo auditable build if the auditable build process is causing resource issues
