What this means is that the JVM has asked the operating system for more memory for something, and the operating system has said No. You might have attempted to exceed the process (or container) limits, or you may have used all of the system's allocatable virtual memory.这意味着 JVM 已向操作系统请求更多 memory 的东西，而操作系统已拒绝。您可能试图超出进程（或容器）限制，或者您可能已经使用了系统的所有可分配虚拟 memory。
It is unclear what the JVM was requesting memory for, but it could have been the stack segments for a thread that it is starting.目前尚不清楚 JVM 请求 memory 的目的是什么，但它可能是它正在启动的线程的堆栈段。
I would check that:我会检查：
- you are not creating too many threads,你没有创建太多线程，
- you are not using some native code library that is leaking native heap memory.您没有使用一些泄漏本机堆 memory 的本机代码库。
