问题描述
老服务器中运行一个系统，tomcat没有任何问题，可是换到新买的服务器上，tomcat就出现了宕机的现象。通过JProfiler监控内存使用，开始发现heap大小合适，只是回收不及时，然后处理了一下回收，现在heap使用基本就在85m大小，没有泄露。catalina.bat中设置的是-Xms800m,-Xmx800m,-XX:NewSize=256m,-XX:MaxNewSize=256mheap设置了800m,现在只用了85m左右，没有再累加，并未出现泄露但是现在又宕机了，原因不明，把tomcat 的log放出来，希望童鞋们帮忙看一下，谢谢！## An unexpected error has been detected by Java Runtime Environment:## EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x7c95b583, pid=3308, tid=4044## Java VM: Java HotSpot(TM)

解决方案
有解决问题，我们现在用的是6.0.26，非安装版
解决方案二：
可以看一下我的这篇文章。内存溢出的http://songfantasy.iteye.com/blog/791808
解决方案三：
换一个tomcat版本试试看吧，以前也碰到过，从这里看来，出问题的地方不象是你的代码Stack: [0x09b30000,0x09b80000], sp=0x09b7ed70, free space=315k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) C [ntdll.dll+0x2b583] C [ntdll.dll+0x2ba81] C [ntdll.dll+0x2b646] C [msvcr71.dll+0x218a] C [net.dll+0x710e] j java.net.SocketInputStream.socketRead0(Ljava/io/FileDescriptor;[BIII)I+0 j java.net.SocketInputStream.read([BII)I+119 j org.apache.coyote.http11.InternalInputBuffer.fill()Z+59 Java frames: (J=compiled Java code, j=interpreted, Vv=VM code) j java.net.SocketInputStream.socketRead0(Ljava/io/FileDescriptor;[BIII)I+0 j java.net.SocketInputStream.read([BII)I+119 j org.apache.coyote.http11.InternalInputBuffer.fill()Z+59 J org.apache.coyote.http11.InternalInputBuffer.parseRequestLine()V j org.apache.coyote.http11.Http11Processor.process(Ljava/net/Socket;)V+234 j org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Ljava/net/Socket;)Z+82 j org.apache.tomcat.util.net.JIoEndpoint$Worker.run()V+58 j java.lang.Thread.run()V+11 v ~StubRoutines::call_stub
