下载 JR 报告时出现 Java 堆空间内存错误

【问题标题】：Java heap space memory error while while downloading JR report下载 JR 报告时出现 Java 堆空间内存错误
【发布时间】：2012-08-21 01:39:03
【问题描述】：

我正在从数据库中获取数据（表 911830 中的记录）并将其添加到 JR 报告中，以便 1000 条记录正常工作。当我超过或某个时间给出 Java 堆空间内存错误作为此问题的标题时，它与 Java 堆内存有关，但我将其增加 3Gb 作为（Xms3072m-Xmx3072m）。但仍然遇到同样的错误

我的系统配置如下：：

  1. 64位没问题
  2. Redhat/CentOS（最新版本）
  3. 120GB 带 RAID 配置
  4. 2GB RAM 和 2CPU 机器

控制台错误::

【问题讨论】：

  • 我正在检查您的配置，当您的物理内存为 2 GB（2GB 的 RAM 和 2CPU 机器）时，您分配 3 Gb 的 RAM (Xms3072m-Xmx3072m) 很奇怪。

标签： java jasper-reports out-of-memory heap-memory


【解决方案1】：

您是否尝试过分析您的应用程序？

尝试进行内存转储并进行调查，也许您的内存中有太多相同类型的对象/一些非常大的对象会占用您所有的内存。

您可以考虑使用 JVisualVM 或您组织中可用的任何其他配置文件

【讨论】：

    【解决方案2】：

    可能比尝试整理内存转储更容易尝试Plumbr。它在发现内存泄漏方面非常好。
