查看python進程運行棧

reference

首先保證進程運行機器上有GDB和pyrasite

# Redhat, CentOS, etc
$ yum install gdb

pip install pyrasite

找到卡住的python進程ID，然後用pyrasite-shell attach上去

# Assuming process ID is 12345
$ pyrasite-shell 12345

進入 python repl 環境，然後輸入

from __future__ import print_function

import sys, traceback

for thread_id, frame in sys._current_frames().items():
    print('Stack for thread {}'.format(thread_id))
    traceback.print_stack(frame)
    print('')
