stap执行失败

[mjay...@gmail.com]

hi，

    请教下，在用sample-bt-leaks.sxx查看进程的内存问题时，总是返回“ERROR: too many pending (error) messages”这个错误信息，这个是什么原因造成的呢？

    printf("Hit %s\n", probefunc()) 返回的打印结果有些是内存地址，不知道和这个有没有关系？

    运行命令：./samples/sample-bt-leaks.sxx -x 3013 --arg time=5 -D STP_NO_OVERLOAD -D MAXMAPENTRIES=10000 > a.bt

    返回结果信息：
