説明

The jvm gets stuck and has to be manually terminated. This happens intermittently and is hard to reproduce.
This issue only happens after upgrading to 1.15.0 (was also seeing issues on 1.15.0-rc2`, 1.14.3 was working fine.
Would appreciate any help with figuring out why this happens.

  3. リポジトリをフォークし、ブランチを切って変更します。
  4. issue 番号を参照したプルリクエストを送ります。

調査の方向性

ResourceReaper.start とスレッドトレースから始め、次に 1.14.3 と 1.15.0 の間で、DockerClientFactory.client と GenericContainer.tryStart を経由する起動パスを比較します。可能であれば、報告された Linux、Docker 19.03.12、Debian 8 の環境で再現してください。断続的なハングの原因を特定し、コンテナの起動が停止したままにならないことを確認できれば完了です。
