各位大虾帮忙！UNIX下的sleep异常？

dirboy_tym

程序一般来说可以运行几天，但是突然有时就over了，
麻烦那位大虾帮我看看，用gdb查看原文如下：
breakpoint in a shared library will not work until you rerun the program.

其中：
appmainctrl.cpp:147的代码是 Thread::sleep(10000);
adresrc.cpp:34的代码是 theApp.start(APPS_TYPE_ADAPTER, false, argv[0]);
adresrc是继承addmainctrl的基类的。
怎么会sleep异常了？望指教
