位于对象等待池中的阻塞状态(Blocked in object’s wait pool): 当线程处于运行状态时,如果执行了某个对象的 wait()方法,Java 虚拟机就会把 线程放到这个对象的等待池中,这涉及到“线程通信”的内容。 位于对象锁池中的阻塞状态(Blocked in object’s lock pool): 当线程处于运行状态时,试图获得某个对象的同步...
5. At the command prompt type 'psexec -s [jdk path]\jstack.exe XXXX >> thread_dump_ddmmyy.log' (where XXXX is your PID and ddmmyy is the current date to append to the name of the log file) then hit enter. Run this command every 5-10 seconds, 5 times You can also add the ful...
jstack -F <pid>puts the target Java process in a "trace stop" (T) state. Threads in the (T) state will receive the signal for a thread dump; however, output will be delayed until the process continues.
一、thread dump信息获取 1、发送信号 * In Unix, use "kill -3 <pid>" where pid is the Process ID of the JVM.(kill 信号列表) * In Windows, press CTRL+BREAK on the window where the JVM is running. 2、通过命令导出文本文件 jps -l 找出服务器上运行的Java进程 jstack -l pid 直接显示在...
