This is occurring on both i386 and amd64 VM's. The description has been updated to this effect.
** Description changed: - This is noticed during health-check's tests on trusty (mostly i386) - ISO's. + This is noticed during health-check's tests on trusty (mostly i386 but + also on amd64) ISO's. The failed builds in https://jenkins.qa.ubuntu.com/view/Trusty/view/Smoke%20Testing/job /trusty-desktop-i386-smoke-health-check/ are all due to this issue. - The following is excerpts from cking's debugging of the failure: "NetworkManager does not show this issue when no connections are made old connections are re-established. Only new connections since reboot seem to trigger this. The large mmap is a bit ridiculous, it's either the heap (via malloc/free) or glib memory allocator being a bit generous in the way it requests more memory for the heap or network manager itself doing a large mmap request (which I think is very unlikely). The good news is that the memory is mapped but not all used, so there is little actual physical demand for these mapped in pages. Even so, I think it may be worth somebody with NetworkManager experience to dig in deeper to see why and where this allocation is occurring as a medium/low bug. To reproduce this issue: 1. Clean boot 2. Wait until existing network connections are established (e.g. wifi) 3. Run health-check on Network Manager 4. Make a new connection, e.g. plug in ethernet connection for an auto-ethernet connection to be established. 5. Stop health-check, observe that a huge allocation has occurred."
