java - JProfiler 7.2.2 远程 JVM 崩溃

Question

我将 Jprofiler 远程连接到 Linux 服务器。但是在连接最终远程JVM崩溃时。JProfiler GUI 的错误消息如下：

The network connection has been lost. The JVM might have terminated unexpectedly.

If the JVM has crashed, please try the following strategies:
*Reduce the -Xmx value of the profiled application.
*Change your profiling settings

我的远程 JVM java 版本是 1.6.0_33 Java Hotspot(TM) 64-Bit Server VM

为什么说要减少已分析应用程序的 -Xmx 值，或者如何解决这个问题？

Answer 1

I had similar problem with JProfiler 7.2.3 after specifying JVM GC settings for JBoss 4.2.3:

-XX:+UseConcMarkSweepGC

-XX:+UseParNewGC

It worked again for me after removal of these settings.
