1.2 RC2 -> RC3 upgrade fails - swap_pager: out of swap space

  • Hi

    When performing 1.2 RC2 -> RC3 firmware upgrade the process fails returning:

    swap_pager: out of swap space
    swap_pager_getswapspace(16): failed
    pid 660 (lighttpd), uid 0, was killed: out of swap space

    Both times i've tried the lighttpd process sits on top @ ~60% cpu, all the while the available physical memory slowly decreases. Virtual memory usage slowly starts to climb and eventually the process fails returning the above error. I've got 128MB physical and 256MB swap configured. From start to death the process takes about 40 seconds.

    Below is dmesg output:

  • Ok, just rebuilt the system w/1G of swap and the upgrade completed ok. Only a warning about the upgrade not being signed and I proceed at my own peril (or something thereabouts).

    Since this was a fresh re-install I had not configured any of my ed interfaces, nor had I set up any other services. I'll perform another re-install, configure the system for all interfaces and services and see what happens when I try and upgrade to RC3.


  • Having configured all interfaces and services (nothing special, just dhcp server at the moment) the upgrade from RC2 -> RC3 completed successfully.

    Having watched top a bit more closely this time I can confirm the following figures for swap usage (taken while watching the screen, so the math may not add up exactly!)

    Swap: 1024M Total, 373M Used, 651M Free, 36% In Use

    The 128MB of physical was exhausted pretty quickly, and 256MB of swap is definitely insuffcient! :)


  • There's a problem right now with an apparent bug in Lighttpd where it chews up a bunch of memory and dies during upgrades. If you run into this, the console upgrade will still work fine. I actually like console upgrade better because you can just paste the URL in and it downloads and upgrades automatically.
