服务器的已经运行一段时间的项目最近开始报这个内存溢出的异常,求解!

图片说明:这个是我服务器的jvm配置

永久代的内存设置大一点。还有其他内存也设置大一点

鬼迷了你心窍 就是楼上是我的内存配置,这个配置不够吗?

公司的系統點擊一個功能的時候報java.lang.OutOfMemoryError: PermGen space
在公司的系統中點擊了一個打印的功能,前臺是用flex,后臺是java,打印的時候是彈出來一個jsp頁面,中間夾了大量的計算。在本地測試沒事 可以彈出來jsp頁面,但是放在測試機上時候就會報如下異常,我在測試服務器的環境變量里設置了 变名:JAVA_OPTS 变量值:-Xms1024m -Xmx1024m 還是沒有作用,不知道應該怎么處理了。是程序的問題嗎? java.lang.OutOfMemoryError: PermGen space at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) at java.net.URLClassLoader.access$000(URLClassLoader.java:56) at java.net.URLClassLoader$1.run(URLClassLoader.java:195) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at org.eclipse.jdt.internal.compiler.parser.Parser.consumeClassHeaderName1(Parser.java:2161) at org.eclipse.jdt.internal.compiler.parser.Parser.consumeRule(Parser.java:5103) at org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java:9020) at org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java:9251) at org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java:9208) at org.eclipse.jdt.internal.compiler.parser.Parser.dietParse(Parser.java:7864) at org.eclipse.jdt.internal.compiler.Compiler.internalBeginToCompile(Compiler.java:587) at org.eclipse.jdt.internal.compiler.Compiler.beginToCompile(Compiler.java:357) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:371) at org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:413) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:317) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:295) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:282) at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:586) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:317) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:342) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:267) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233)
关于java.lang.OutOfMemoryError: PermGen space的问题
昨天在测试做一个审批流程过程中突然报了java.lang.OutOfMemoryError: PermGen space的错误。![图片说明](https://img-ask.csdn.net/upload/201708/23/1503476599_700481.png)![图片说明](https://img-ask.csdn.net/upload/201708/23/1503476607_47576.png)![图片说明](https://img-ask.csdn.net/upload/201708/23/1503476613_777099.png)![图片说明](https://img-ask.csdn.net/upload/201708/23/1503476621_918731.png) 上面是错误日志截图 我本机的测试环境跑了近一年了,都没出这样的问题。 其中at com.wondersgroup.cim.innerManager.action.InnerManagerAction.itemChangeAuditPass(InnerManagerAction.java:2635)这做的是一个常规的数据库更新操作, at com.wondersgroup.cim.common.utils.SendMessageUtil.doLogin(SendMessageUtil.java:57) at com.wondersgroup.cim.common.utils.SendMessageUtil.sendMessage(SendMessageUtil.java:28)这做的是一个调用web service操作。 另外我没有额外配置PermSize和MaxPermSize,都是默认值。 这个问题到底是怎么产生的,不应该是JVM内存问题啊,如果是内存溢出,那么这个问题是会经常出现,但我就昨天出现了一次,在怎么也还原不出这个错误了, 请问各位大神,这是怎么个情况

内存溢出问题,不知道是哪里出现的问题,怀疑是druid连接池使用不当,求大佬帮忙。
昨晚上出现了两次内存溢出,找不到复现的方法,每次出现内存溢出都不一样,两次都是先出现"Disk Write of"写入磁盘失败错误,然后就是druid获取连接失败,然后报OOM异常,接着linux服务器cpu使用率上涨,一直涨到百分之600满(服务器是6核CPU),第二次的日志看跟第一次出现类似;下面是第一次 日志 2020-03-16 17:39:47 ERROR [DiskStorageFactory.java:495] -

SSH 框架,查询多条记录并执行删除操作,删除之后再进行刷新。重复“删除”、“刷新”造成内存溢出
使用SSH框架开发一个后台管理系统。有个管理新闻的模块。需要查询全部新闻,单条或者批量删除,然后重新查询显示新闻。重复几次就会崩掉。控制台显示下面的异常。有些数据量很小的查询、删除,重复几次也会出现这个状况。网上也找了一些解决方法,比如在tomcat中设置内存大一些。但是不管用。求教~~~ 下面是异常: Exception in thread "http-apr-8080-exec-6" java.lang.OutOfMemoryError: PermGen space at java.lang.ClassLoader.findBootstrapClass(Native Method) at java.lang.ClassLoader.findBootstrapClassOrNull(ClassLoader.java:1070) at java.lang.ClassLoader.loadClass(ClassLoader.java:414) at java.lang.ClassLoader.loadClass(ClassLoader.java:412) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:412) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at org.apache.catalina.valves.ErrorReportValve.report(ErrorReportValve.java:173) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:133) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:936) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:407) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1004) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:589) at org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:1852) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744)
