Christopher, I did such a test back in March upon request with no response to my testing results then. Nor *any* activity, until your recent notes. Do we have any specific reason or bugfix to believe that this memory issue has been addressed since then? Will I get at least a response this time to my testing results as to next steps? I ask because this test can take several days to perform and I will not be able to start it immediately, I want to make sure its worth our time to do in order to get the most effective progress on this.
BTW, have you noticed the bug report below? It seems fairly similar to what I've been seeing in different kernels/testing as well as has a similar reproduction method. In my testing there definitely is the OOM deadlock in my 2.6 kernel testing while the 3.2 kernel testing seemed to have a slightly different "deadlock" in believing it had made page freeing progress when in fact it had not done so. My upstream kernel testing back in March had not totally deadlocked, but would "freeze" for long periods of time. Here's the kernel.org bug, with no response, that seemed somewhat similar and could be an indication that me doing upstream testing would not be all that useful: https://bugzilla.kernel.org/show_bug.cgi?id=59901 Assuming a positive response for me to still proceed with the upstream testing you requested, I will first have to reconfirm that my current testbed can reproduce the issue with the latest 3.2 -51 Ubuntu kernel and then I will try the upstream kernel you referenced. So it will be a little while before I can report on this testing, which took multiple days in the past. Nor can I start this testing immediately. It sure would be nice if you guys could reproduce this, I thought my info on this score would be adequate for that. -- Marc -- On Fri, Aug 9, 2013 at 7:35 PM, Christopher M.
