SYMPTOMS
When you try to remove the files of a network file system (NFS) shared resource, not all the files are removed. You have to run the rm -rf command again to successfully remove the remaining files.



CAUSE
The problem is caused by a rare condition where both the RMDIR request and the READDIR request are sent to the same directory.

If READDIR arrives while RMDIR is processing the removal of the files, READDIR updates the in-memory cache in such a way that RMDIR eventually fails. If you try to use the RMDIR request a second time, the directory is removed (unless another READDIR request occurs at the same time).



RESOLUTION
To resolve this problem, flush the directory from the in-memory cache before you remove the corresponding directory. The next READDIR request is unsuccessful, instead of being successful and causing the problem.
