Steps to reproduce

Trying to build the package for alpine 3.21-aarch64 gets a few failures, not always at the same place.

Build logs are ephemeral so copying:

Research direction
The issue describes test failures on Alpine 3.21 in TestTLSMemLeak (socket test.go) and TestGetStackdriverIntervalEndpoints (stackdriver test.go). The failures are flaky and related to memory comparison and time sensitive intervals. Check the issue comments for any suggested fixes. Review the test files to adjust tolerances or skip the tests on Alpine if they are not representative. The tests might need to be made more robust for different environments.
