Linux环境下通过gstack命令查看进程的运行堆栈信息

NAME
gstack - print a stack trace of a running process

SYNOPSIS
gstack pid

DESCRIPTION
gstack  attaches  to the active process named by the pid on the command line, and prints out an execution stack trace.  If ELF sym‐bols exist in the binary (usually the case unless you have run strip(1)), then symbolic addresses are printed as well.

If the process is part of a thread group, then gstack will print out a stack trace for each of the threads in the group.
