虽然这是各种Stackoverflow用户报告的典型错误消息，但我的问题与如何评估提议的解决方案是否能解决问题有关。
我阅读了各种讨论＆amp;与此错误相关的文章和大多数解决方案深入到Linux ulimits，我想这似乎也适用于我。
我的ulimit值是：
STACK 10240k, CORE 0k, NPROC 1024, NOFILE 4096;
我想问题可能是NOPROC / NOFILE太低（只有默认值）。
但是，我想知道是否有确切的方法来确定根本原因，例如NOPROC已被超过等等，以及是否有办法准确评估当前正在使用多少个进程/文件句柄;或者是否还有一些我应该关注哪些问题可以进行统计评估？
仅供参考，发生此问题时，未启用heapdump，并且在出错时没有任何线程数据。
感谢您对评估和解决此问题的投入。
