在分析进程的核心（由信号 6 终止）时，在 LINUX 上，堆栈 bt 显示：

Core was generated by `/opt/namsam/pac_rrc_qx_e1/bin/rrcprb'.

Program terminated with signal 6, Aborted.

#0  0x0000005555ffb004 in epoll_wait () from /lib64/libc.so.6

(gdb) bt

#0  0x0000005555ffb004 in epoll_wait () from /lib64/libc.so.6
#1  0x0000005555ffafe8 in __epoll_wait_nocancel () from /lib64/libc.so.6
#2  0x0000005555ffafe8 in __epoll_wait_nocancel () from /lib64/libc.so.6
#3  0x0000005555ffafe8 in __epoll_wait_nocancel () from /lib64/libc.so.6

#7  0x0000005555ffafe8 in __epoll_wait_nocancel () from /lib64/libc.so.6

libc 似乎进入了某个循环.. 这里的应用程序“rrcprb”出了什么问题..？请帮我调试这个问题..？

由于__epoll_wait_nocancel不调用自身，很明显你得到的堆栈跟踪是伪造的。最可能的原因是您的libc.so.6.

您实际上也不太可能坠入epoll_wait. 试试看thread apply all where，看看是否有“更有趣”的堆栈跟踪/线程供您查看。
