Just in case processes will not respond on kill -QUIT again: you could try "strace" and "gstack". If the process still does issue system calls, you can get those with strace (and maybe get an idea what it is doing), if it is hanging somewhere in native code, you could look at it with gstack. If it is hanging in Java code, neither strace nor gstack will help. > But back to the ArrayList, how high is the probability of having > ArrayList.size() twice in the similar call-tree in one ThreadDump? Tell us the whole stack, not just the top line.
