I think Andrew is referring to my team in comment #7 (my NFS exports are on an ext3 partition). I can confirm that mainline kernel 3.2.27-generic does *not* resolve the leak, as I recently noticed the leak again. I think it was a NFSv3 vs. v4 issue, as many of my clients moved back to v3 as an attempt to resolve the issue. But a few rarely-utilized clients remained, and it seems that NFSv4 activity from these clients correlates with memory leakage in idr_layer_cache.
So, I've seen the leak on all the following: 3.2.0-30-generic 3.2.0-29-generic 3.2.27-030227-generic The last kernel is a vanilla build from the Ubuntu PPA: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2.27-precise/ So, I think that this is an upstream leak, at least in the 3.2.x stable branch. -- 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/nfs-utils/+bug/1047566/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
