Apache flink &引用；“缓冲池被破坏”；Apache Flink flapMap运算符中发现问题

当我尝试在flatMap操作符中写入OUT集合时，我得到非法状态异常（仅在高负载下）：缓冲池被破坏 我怎么会在这里？当flink抛出缓冲池错误时

java.lang.RuntimeException:  Buffer pool is destroyed.

什么是缓冲池

缓冲池是网络堆栈的内存段实例的固定大小池，这意味着您在发送数据时将段放入其中，在通过网络接收数据时从中提取段

为什么会被摧毁

由于网络环境关闭，缓冲池被破坏

为什么网络环境会关闭

这可能是一个具体的情况，我不是很确定。我建议您阅读此缓冲池异常上面的更多日志。

如果没有代码，我无法给出任何建议。
