Bluefoxicywhy does Google Maps lock up either Chromium or my whole desktop?00:37
Bluefoxicyyou know, by maxing out RAM usage whenever I open a tab to it and try to scroll wheel in00:38
sithlord48its got a fevor and its only cure is more RAM?00:38
BluefoxicyI've also found that disabling swap doesn't help:  RAM bloats, pushes out page cache, then the hard disk thrashes re-reading libraries CONSTANTLY.  Why isn't there a page cache lock to OOM in favor of freeing page cache?00:39
BluefoxicySeriously I have 16GB RAM.  The kernel is too stupid to understand that 50MB of page cache and 16.950GB of working memory is going to kill the machine.00:39

sarnoldBluefoxicy: you could always use ulimit -m   to limit chromeium to just eight or ten gigs or whatever00:43
sarnoldBluefoxicy: maybe ulimit -v would be better. either way it's worth a shot00:44
Bluefoxicysarnold:  it doesn't work that way02:14
Bluefoxicysarnold:  you can limit the VMA--preventing mapping of file-backed segments et al, which is used for file caches and so forth, which is managed by the kernel--or you can limit nothing.02:15
BluefoxicyTrying to limit resident set size of memory per-process or per-user on Linux is really useless.02:15
BluefoxicySecond, the point is that the kernel will swap-thrash when you eat up memory even when you have no swap.02:15
Bluefoxicysarnold: btw, ulimit -m doesn't do anything02:17

mlankhorstinfinity: those kind of patches should really have been submitted with a cc to stable, to get it in 10.3 automatically04:32
sarnoldBluefoxicy: aww, I thought the -m limits had been put back around 2.6.17 era :/06:34
infinitymlankhorst: Fair enough, not my patch, but can we carry it anyway? :P07:50
mlankhorstsure11:42
mlankhorstI won't carry it, but I can commit it to mesa11:42

geofftxnox: Logan_: can your capnproto delta be submitted to Debian? want me to file a bug in the BTS?19:51
Logan_lemme check19:51
geofftDebian has 0.4.1, so it seems like it'd be nice to be able to sync19:52
Logan_it looks like my delta was already incorporated19:52
Logan_they're using dh-autoreconf in Debian now as well19:52
Logan_not sure about all of Dmitri's stuff, though19:53
