Question

我有一个多线程的java应用程序，它产生的线程与在某个时刻完成的报告一样多。在流程结束时，我使用带有WorkbookFactory.create(file)的Apache POI（3.15）生成Excel文件，其中file是我用来创建全新Excel文件的空模板。使用特定的密集型报告（生成需要数小时），当代码到达此点时，它会抛出此异常：

Caused by: java.nio.channels.ClosedByInterruptException

    at sun.nio.ch.FileChannelImpl.read(FileChannelImpl.java:163)

我在某处读过可能与limits.conf文件有关的内容。你对如何调查这个有什么建议吗？当前值：
