Thanks Anders. The upgrade to 14.04 worked. I upgraded to
3.13.0-34-generic and SUnreclaim is no longer climbing. So, if anyone
has a similar issue to me, the upgrade to the 14.04 kernel seems to work
- or at least it did in my case.

Hey John. We had the same problem with extremely low load. Some form of
leak. Never found a good solution (besides reboot when leak reaches
critical as a work around). For the exact same purpose (code/file
transfers) running on Ubuntu 14.04 is much better. I recommend you
upgrade unless you can fix

We have seen this for many months now. The only workaround we have found
is, as mentioned, to reboot when memory is reaching a crash.
The release below did not work.

I've recently been wondering why my kvm server runs out of memory when I

I believe the Ubuntu 3.2.0-34 kernel now should contain the upstream
commit (see bug #1075355). I'm not using NFSv4 anymore (because of this

myself...
Can anyone else confirm that this is fixed in the repos?

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

I spoke with someone else who had this same issue on both
3.2.0-29-generic and 3.2.0-30-generic (Ubuntu-specific kernels). He was

ext4. This person reports switching to the mainline kernel, version

I was hesitant to say that this is definitely an NFS issue, since it
might also be an EXT4 issue (judging by the fact that ext4_inode_cache

Need to test this without EXT4.
