This sounds unlikely. There are lots of reasons a subdirectory cannot be 
created (e.g., permissions problem), and whatever syscall failed, rm 
surely used perror or strerror or whatever.

What happens if you run something like these shell commands with the 
problematic directory? (You may need to be root.) I am interested in the 
system call that occurred just before 'rm' outputs a diagnostic.

export LC_ALL=C
ktrace rm -rf confdir-14B---
kdump

I don't think that would help, as I don't think the file system was 
actually full.
