 Posted: Fri Dec 22, 2006 11:49 am Post subject: cannot kill -9 on AMD64 with 3gig |
 |
|
Hi all,
The story goes like this:
I have an AMD64 on an Abit AV8 K8T800 Pro/8237 1000 MHz FSB, with Gentoo Linux 2.6.18-r4 installed with genkernel. Kernel and system binaries are x86_64 (so no HIGHMEM flag required).
Everything worked fine until i decided to do a RAM upgrade. I now have 3GB (dual channel enabled). System works fine until memory process alloc goes beyond 2GB limit. Then, my processes do not respond (for example apache is receiving requests but never responding, it just waits). But it gets worse, i cannot kill them as root, even kill -9 [pid] or killall -9 [pname] do not have any effect! Processes do not get killed, do not free memory, and of course, because of this, shutdown -r (restart) has no effect. I have to reset the server from the button.
This has happened with 2.6.12 too, thats why i decided to upgrade to 2.6.18, but to no effect. I could not find too much docs about why killall -9 does not kill stuff. My assumption is that something goes wrong when server allocates more than 2GB of RAM but i have no idea what it can be. The memory modules are Kingston pairs, so i am confident they are good quality. Syslog is totally quiet, no suspicious messages from the kernel there.
These are my grub.conf lines:

It seems there is some bug in kernel that causes the processes deadlock in signal handler (and therefore don't receive another signal). Append your dmesg, there should be more info.

Try enabling the HIMEM flag and see if that affects it.

It's not available in x86_64, I assume it doesn't have the drawbacks of needing a special HIMEM thing like 32bit did. |

hi,
thanks for the replies.
yes, the HIMEM flag is not available for x86_64 architecture. i will try to add it manually to .config but since it does not appear in the menuconfig it might get ignored.
here's my dmesg:

this does not look normal, has anyone had this problem before ? any clues ?
thanks,
mihai |
