Heap size 的大小是Young Generation 和Tenured Generaion 之和。 提示:在JVM中如果98%的时间是用于GC且可用的Heap size 不足2%的时候将抛出此异常信息。 提示:Heap Size 最大不要超过可用物理内存的80%,一般的要将-Xms和-Xmx选项设置为相同,而-Xmn为1/4的-Xmx值。 解决方法:手动设置Heap size 修改TOMCAT_H...

As a test I ran "java -Xmx1024m -version" from the command line and it fails too. If I run "java -Xmx512m -version" it succeeds. It's almost as if I can't set the max heap size to anything above 700MB. How to I get it to 1GB so the java app we require launches?
