| |
Dear programmers,
I don't subscribe to this mailing list, but I have a minor question about kswapd of kernel-2.2.0-pre6/pre7. I found that the kill command like
kill -9 3 killall5 -9
will cause the process kswapd to become zombie. But in kernel-2.0.X, kswapd seems to ignore the SIGKILL signal. It might cause some problems, since sometimes we would like to switch to single user mode to maintain system, but /etc/init.d/ scripts will use killall5 to send the SIGKILL message before going to the single user mode, and the kswapd dies.
Now we quick hack the source of killall5 such that it doesn't send the SIGKILL signal to process 3 (kswapd). But I don't think this is a good idea. Is there any other suggestions?
My system: Debian/GNU Linux-2.0
kernel-2.2.0-pre7 Kernel modules 2.1.121 Gnu C 2.7.2.3 Binutils version 2.9.1 Linux libc6 C Library 2.0.7t-1 Dynamic Linker (ld.so) 1.9.9 Linux C++ Library 2.7.2.8 Procps 1.2.9 Psmisc 17 Net-tools 1.49 Sh-utils 1.16 NFS 2.2beta34 Bash 2.01.1(1) PPP 2.3.5 Util-linux 2.9g
Thank you very much for your reply in advance.
