This post ties up a few loose ends in this thread which remained after my 21 March 2013 post. * The memory leak was not present in 2.6.36. * The patch to 2.6.35.11 at the end of this email (based on 48e6b121605512d87f8da1ccd014313489c19630 from linux-stable) resolves the memory leak in 2.6.35.11. This gives us a workable solution while we await fixes to current mainline in the r8169 driver. Once that's done we can revalidate our systems against a more recent kernel and start shipping that. Thanks to those who assisted with this issue.
