在Linux环境中使用Java中的Runtime.getRuntime（）.exec执行命令时出现内存泄漏问题

我使用下面的代码从Java运行Linux命令，但是我得到了内存泄漏错误。PFA错误和代码。如果你已经面对这个问题，请给我一些解决方案

SEVERE: The web application is still processing a request that has yet to finish. This is very likely to create a memory leak. You can control the time allowed for requests to finish by using the unloadDelay attribute of the standard Context implementation.

你的问题的根本原因是

Caused by: java.io.IOException: error=2, No such file or directory
    at java.lang.UNIXProcess.forkAndExec(Native Method)
    at java.lang.UNIXProcess.<init>(UNIXProcess.java:135)
    at java.lang.ProcessImpl.start(ProcessImpl.java:130)
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:1023)

原因：java.io.IOException:error=2，没有这样的文件或目录
位于java.lang.UNIXProcess.forkAndExec（本机方法）
位于java.lang.UNIXProcess（UNIXProcess.java:135）
在java.lang.ProcessImpl.start（ProcessImpl.java:130）
位于java.lang.ProcessBuilder.start（ProcessBuilder.java:1023）

问题是由于您试图运行的脚本命令，它正在查找无效目录，而您得到的

IOException

不存在此类文件或目录。确保提供了正确的路径并再次尝试启动apache

错误“不存在这样的文件或目录”是由错误的文件夹引起的。即使命令执行成功，我也会遇到内存泄漏问题。问题在于runtime.exec。如果你能建议一些替代方案，那就太好了。你正在运行多少个apache实例？apache使用的端口是否已与其他进程共享。。？运行多个apache实例会导致问题..并指定您的系统内存和apache进程消耗的内存量您知道如何检查apache实例的数量吗？@sathurya by instances我指的是您在系统中安装的“apache程序”的数量..如果您一次启动了多个apache时间会导致内存泄漏问题..因为运行apache的一个实例会消耗更多内存（RAM）以及apache使用的端口..检查该端口是否与其他应用程序共享..请更新完整的类代码和异常堆栈跟踪。。
