Java 运行时环境内存不足，无法在 Tomcat 中继续
Insufficient memory for Java Runtime Environment to continue in Tomcat
本人是tomcat/技术新手，如有问题描述有误请见谅
我正在尝试 运行 仪表板应用程序 DOMO 在我们的测试服务器上。十年来，我们一直在使用 tomcat 到 运行 应用程序，通常一切正常。最近，当我尝试 运行 应用程序时，它不会 运行。我清除了工作目录并再次尝试运行 tomcat。没有任何效果，DOMO（仪表板工具）的应用程序日志出现以下错误：

系统错误日志如下所示：
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 32744 bytes for ChunkPool::allocate
# Possible reasons:

我已经阅读了很多关于相关主题的帖子，但是自从我在过去十年中申请 运行ning 以来，突然出现这个问题对我来说真的很奇怪。此外，这个环境就像一个测试服务器，目前我是唯一一个将它用于仪表板的人。因此，系统负载增加的可能性似乎不正确；也没有内存泄漏的可能性。
任何人都可以指导我在这种情况下可能出了什么问题吗？
谢谢！
编辑：我认为我的问题是不同的，因为它不是要分配一些新的内存块，而是一个 ChuckPool::allocate 操作，它突然停止工作，即使在服务器上没有引入新负载。
JVM 的最小和最大堆大小是多少？由于 JVM 堆内存不足而发生内存不足错误。 OS 和 Tomcat 是什么？它是 32 位 OS 吗？另外，系统上的 RAM 内存是多少？
32 位 OS 假设 4GB 或更高的 RAM，最大 JVM 堆大小只能是 1.5GB。因此，将最大和最小堆内存大小调整为 1.5 GB 可以缓解该问题。由于您确定没有内存泄漏，您应该考虑为您的应用程序选择正确类型的 GC 收集器 - 基于吞吐量的 GC 或其他（并行等）并优化暂停时间和收集。这将使 JVM 有足够的空间用于新对象分配，而不是 运行 内存不足。

我已经阅读了很多关于相关主题的帖子，但是自从我在过去十年中申请 运行ning 以来，突然出现这个问题对我来说真的很奇怪。此外，这个环境就像一个测试服务器，目前我是唯一一个将它用于仪表板的人。因此，系统负载增加的可能性似乎不正确；也没有内存泄漏的可能性。
任何人都可以指导我在这种情况下可能出了什么问题吗？
谢谢！
编辑：我认为我的问题是不同的，因为它不是要分配一些新的内存块，而是一个 ChuckPool::allocate 操作，它突然停止工作，即使在服务器上没有引入新负载。
JVM 的最小和最大堆大小是多少？由于 JVM 堆内存不足而发生内存不足错误。 OS 和 Tomcat 是什么？它是 32 位 OS 吗？另外，系统上的 RAM 内存是多少？
32 位 OS 假设 4GB 或更高的 RAM，最大 JVM 堆大小只能是 1.5GB。因此，将最大和最小堆内存大小调整为 1.5 GB 可以缓解该问题。由于您确定没有内存泄漏，您应该考虑为您的应用程序选择正确类型的 GC 收集器 - 基于吞吐量的 GC 或其他（并行等）并优化暂停时间和收集。这将使 JVM 有足够的空间用于新对象分配，而不是 运行 内存不足。
