Linux 2.2.18, pcmcia-cs-3.1.21, Pentium 75 (100 MHz) Toshiba 420CDS Satellite Pro laptop, 40 MB RAM
I can get this to happen reliably:
kernel: VM: do_try_to_free_pages failed for xntpd... kernel: VM: do_try_to_free_pages failed for klogd... last message repeated 15 times kernel: VM: do_try_to_free_pages failed for tail... last message repeated 15 times kernel: VM: do_try_to_free_pages failed for init... last message repeated 15 times kernel: VM: do_try_to_free_pages failed for vmstat... ... etc.
It happens when swap gets full (I have 32 MB swap); I have a particular program that thrashes the system (balanced binary tree searching) so there's heavy swapping going on. Once, running 2.2.18pre23, this happened when I wasn't looking, and when I came back the system was dead -- I'm not sure what the message means or how long it could survive after that, but I run apmd/noflushd, and the disk & screen were powered down. I got the disk to spin back up, but nothing else happened. I just made do_try_to_free_pages fail again under 2.2.18, but I quit & rebooted before anything else happened.
Can enough do_try_to_free_pages failures do that? Are they supposed to happen at all? Do I need to configure some out-of-memory thing?
