linux中线程死锁定位

1.查看进程id

[gm@gm ~]$ ps -ef

2.启动gdb attach 进程

[gm@gm ~]$ gdb attach 199187

3.查看所有线程

(gdb) info threads

4.进入某个线程

(gdb) thread 2

5.查看线程调用栈

(gdb) bt
结果
#0  0x00007f566b49a02d in ?? () from /usr/lib64/libpthread.so.0
#1  0x00007f566b4934a1 in pthread_mutex_lock () from /usr/lib64/libpthread.so.0
#2  0x00007f565c53931c in DataOperMgr::IsSubscribeAttr(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) ()
   from /home/gm/GM1000_DAP/Platform/libObjectAccess.so

或者直接用pstack 进程id
