【问题描述】：
我一直在大型机上的 COBOL 程序中使用 z/OS 客户端 Web 启用工具包成功调用外部 REST API（非 HTTPS）。但是，我遇到了一种情况，即对同一 API 的请求失败并出现错误 HWTH-COMMUNICATION-ERROR（返回码 262）。
这是我在诊断区看到的：
- 请求失败 (HWTHRQST)
- 返回码：262（HWTH-COMMUNICATION-ERROR）
- 服务：000524288
- 原因代码：140
- 原因描述：EDC5140I 管道损坏。
我无法判断是什么导致它仅在某些情况下失败。谁能帮我理解问题可能是什么？
这是失败的执行的详细日志：

我们在 E15/E35-SORT-exits 中尝试使用工具包时确实遇到了类似的问题。结合一些 IBM 文档显示，不支持在 SORT 环境中使用该工具包（我认为它确实包括使用数据集的 COBOL SORT 语句）。
