Question

我在Windows 7上安装了jprofiler 9，我试图在离线模式下远程配置在远程linux上运行的JVM。

我在JVM参数中添加了JVM参数，如下所示。并将二进制文件和config.xml复制到linux框中。

#Jprofiler Settings
JAVA_OPTIONS="-agentlib:jprofilerti=port=8849,nowait -Xbootclasspath/a:/home/jprofiler9/bin/agent.jar -agentpath:/home/jprofiler9/bin/linux-x64/libjprofilerti.so=offline,id=108,config=/home/.jprofiler9/config.xml  ${JAVA_OPTIONS}"
export JAVA_OPTIONS
export LD_LIBRARY_PATH=/home/jprofiler9/bin/linux-x64:$LD_LIBRARY_PATH

现在，当我启动服务器时，我遇到了分段错误并且它转储核心，输出日志在

1）在使用GUI的在线模式下，服务器启动，我可以获取配置文件。但是，当服务器启动时，我将Jprofiler与服务器分离，一旦服务器启动，我再次连接并获取配置文件。那么在离线模式下是否有分离和附加功能？

请注意，服务器启动堆大小为8GB

2）所以在离线模式下服务器实际上是在尝试捕获CPU配置文件，因为在日志中它表示＆＃34; JProfiler＆gt;启用CPU配置文件＆＃34; 。这可能是服务器启动失败的原因，分段错误

Answer 1

您加载本机代理库两次。这意味着您传递两个-agentlib：jprofilerti参数或另一个加载代理库的-agentpath参数。
