请问能否帮忙确定一下是不是JVM版本问题

回复 6# Batcher


    java的版本时1.7收起

回复 7# lifang722324


    搜索线程的状态，一般线程有Deadlock,Runnable,Waiting on condition,Waiting on monitor,Suspended,Object wait(), Blocked,Parked, 重点关注下Blocked，看被什么线程阻塞，然后阻塞他们的线程在做什么事情，一般及可定位问题。收起

回复 5# 请叫我航哥


   从哪个地方可以看出来有没有现成阻塞收起

/opt/IBM/WebSphere/AppServer/java/bin/java -version

结果贴出来看看收起

随便找个编辑器打开就行了，关键看有没有线程被阻塞。收起

回复 3# fm928


    那又什么其他解决方法嘛？收起

估计是你的javacore文件不完整，我碰到过的。不知道什么原因。收起

先看看这个大小是不是0 是空的 然后可以手动多杀出几个收起
