Linux Kernel Segfault Error 6

you get. So you have a message like the following: segfault at bfea3fec ip 080ee07e sp bfea3fa0 error 6 You might
Kernel Segfault Error 4
already know that ip means instruction pointer and sp means stack pointer segfault at ip sp error 4 and as such the addresses that follow them are the values in those registers. But what does the
Kernel Segfault At Rip Rsp Error 4
error number mean? The error number, or code, actually gives you a better explanation of what the cause of the segfault is. The number's bits are flags describing the segfault at rip rsp error 6 error and are architecture-dependent. For x86/x86_64 I just wrote an online converter/decoder that you can use to explain the segfault error code. As an example, the above error code is explained as: The cause was a user-mode write resulting in no page being found. And the common error 4: The cause was a user-mode read resulting in no page segfault error 14 being found.(also known as a null pointer dereference). Enjoy.

echo 10.100.123.11 > /tmp/master
sleep 5
updateMaster
}
updateMaster
Now, that's called from different script:Code: Select all
deamonToKeepMasterAlive() {
touch /tmp/updatemaster.sh
echo "updateMaster() {" > /tmp/updatemaster.sh
echo "echo kernel segfault error $SRV > /tmp/master" >> /tmp/updatemaster.sh
echo "sleep 5" >> /tmp/updatemaster.sh
echo "updateMaster" >> /tmp/updatemaster.sh
echo "}" >> /tmp/updatemaster.sh
echo "updateMaster" >> /tmp/updatemaster.sh
chmod +x /tmp/updatemaster.sh
exec /tmp/updatemaster.sh &
}
Idea was to keep an file with fresh, max 5 sec, time stamp. Yeah, it's simple and possibly I could do loop to run 11 times and be called from cron to make it for a minute but that was quicker (and it was Friday so there you go!)But why it's segfaulting? Any ideas?CheersChrisEverything updated.[root@mv-mb1 ~]# cat /etc/issueCentOS release 5.3 (Final)Kernel \r on an \m[root@mv-mb1 ~]# uname -aLinux mv-mb1.mvg.local 2.6.18-128.1.16.el5 #1 SMP Tue Jun 30 06:07:26 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux Top pschaff Retired Moderator Posts: 18276 Joined: 2006/12/13 20:15:34 Location: Tidewater, Virginia, North America Contact: Contact pschaff Website segfault error 6 - bash script Quote Postby pschaff » 2009/07/14 14:41:00 columb wrote:...
