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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1047566 Title: Memory leaks when using NFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1047566/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
