RuntimeError: can't start new thread #447
Description
我在x86 服务器（openEuler 22.03 (LTS-SP3)）上通过以下命令启动opensandbox-server，经验证8080端口可用。
docker run -d \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /data/opensandbox/sandbox.toml:/etc/opensandbox/config.toml \
-p 8080:8080 \
sandbox-registry.cn-zhangjiakou.cr.aliyuncs.com/opensandbox/server:v0.1.1 \
--name opensandbox-server
然后在Java代码中引用代码解释器Kotlin SDK，使用示例代码执行。
public static void main(String[] args) {
// 1. 配置连接信息
ConnectionConfig config = ConnectionConfig.builder()
.domain("127.0.0.1:8080")
.apiKey("c36f32be8c464a50a96bd2e94ce4cb7e")
.build();
// 2. 创建 Sandbox 实例
// 注意: 必须使用 code-interpreter 专用镜像
// 使用 try-with-resources 确保资源正确关闭
try (Sandbox sandbox = Sandbox.builder()
.connectionConfig(config)
.image("sandbox-registry.cn-zhangjiakou.cr.aliyuncs.com/opensandbox/code-interpreter:v1.0.1")
.entrypoint("/opt/opensandbox/code-interpreter.sh")
.env("PYTHON_VERSION", "3.11") // 指定语言版本
.build()) {
// 3. 创建 CodeInterpreter 包装器
CodeInterpreter interpreter = CodeInterpreter.builder()
.fromSandbox(sandbox)
.build();
// 4. 创建执行上下文 (Python)
CodeContext context = interpreter.codes().createContext(SupportedLanguage.PYTHON);
// 5. 运行代码
Execution result = interpreter.codes().run(
RunCodeRequest.builder()
.code("import sys; print(f'Running on Python {sys.version}')")
.context(context)
.build()
);
// 6. 打印输出
if (!result.getLogs().getStdout().isEmpty()) {
System.out.println(result.getLogs().getStdout().get(0).getText());
}
// 7. 清理资源
// 注意: kill() 会立即终止远程沙箱实例；try-with-resources 会自动调用 close() 清理本地资源
sandbox.kill();
} catch (SandboxException e) {
// 处理 Sandbox 特定异常
System.err.println("沙箱错误: [" + e.getError().getCode() + "] " + e.getError().getMessage());
} catch (Exception e) {
e.printStackTrace();
}
}
报错信息如下：
