问题 I have a handful of heap dumps that I am analyzing after the JVM has thrown OutOfMemory exceptions. I'm using Hotspot JDK 1.7 (64bit) on a Windows 2008R2 platform. The application server is a JBoss 4.2.1GA, launched via the Tanuki Java Service Wrapper. It is launched with the following arguments: wrapper.java.additional.2=-XX:MaxPermSize=256m wrapper.java.initmemory=1498 wrapper.java.maxmemory=3000 wrapper.java.additional.19=-XX:+HeapDumpOnOutOfMemoryError which translate to: -Xms1498m
