We get this error from "ls":
root# ls -f
ls: Memory exhausted
with "top" and "xosview" we see that "ls" grows until
it consumes all available memory (256 Mbytes) and dies
with the above error.
The directory with this problem is NFS mounted from
an SGI running IRIX 6.5.7m. The directory is located
on an XLV logical volume and contains about 2000 files.
Other directories with fewer files seem to be fine.
Further details on mount options, disk sizes, etc...
are available upon request to firstname.lastname@example.org
Looks like an interoperability bug between the nfs implementations in the
Known SGI problem. They sometimes duplicate directory keys and that causes an
infinite directory size!
