@wyang007 Hello, I found that the glibc and glibc debuginfo version was different. Here is gdb message after installing.

(gdb) where

I think that the xrootdfs_create function on XrdFfsXrootdfs has a bug due to a lack of the return value checking.

On https://github.com/xrootd/xrootd/blob/master/src/XrdFfs/XrdFfsXrootdfs.cc#L442,
the res did not be checked after calling of xrootdfs_do_create. If xrootdfs_do_create is failed, fd can be 0.
