Comment 20 for bug 1047566

I could not reproduce this problem, and will need some sort of reproduction procedure in order to pursue it further.

I created a filesystem with 680666 randomly named 4k files, spread out among 6811 nested directories at a max depth of 5 levels of directories.

I exported the filesystem using the following options
/nfs 192.168.122.1/24(rw,no_root_squash,no_subtree_check,async)

And mounted it with the following mount options. (rw,vers=4,addr=192.168.122.186,clientaddr=192.168.122.115)

I then spawned 10 threads on the client running
<<<<<<<<<<<<<<<<<<<<<<<<
#!/bin/bash
find ./ -type f | while read line
do
        cat $line > /dev/null
done
>>>>>>>>>>>>>>>>>>>>>>>>

I could not get the idr_layer_cache to increase above 890k. I am running the following kernel- 3.2.0-53-virtual.
