CentOS 5 :: Cron Errors - Segmentation Fault, Floating Point Exception
Dec 7, 2009
I'm running CentOS 5.4.In the last three days I've started to get various cron errors:
/bin/sh: line 1: 7066 Segmentation fault /usr/local/scripts/cron.email.sshd.access/cron.email.sshd.access.pl
/bin/sh: line 1: 4822 Floating point exceptionsudo -u mobile getmail --quiet
Can't load '/usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi/auto/RRDs/RRDs.so'
[code]...
Then yesterday I rebooted, and all the other errors seemed to have disappeared for now, but, I am now getting:
/bin/sh: line 1: 23600 Segmentation fault sudo -u mobile getmail --quiet
I have setup cron to call getmail once every 3 minutes, and I get this error about 4-6 times an hour.

pidgin started crashing today for no apparent reason. It just shutdowns. No freezing or anything, it just goes away, disappears. From what I can say, there's no specific trigger for this, it can happen after 2 or 10 min after I started it. Once it even shutdown right 10seconds. I tried to run it from the terminal. When I do that, the only thing that appears before closing is
Code:
Floating point exception Anyone has an idea of what it can be? I made no upgrade to pidgin or libpurple recently. I made however an upgrade today of the following packages

I am using a gateway server, 1st NIC eth0 which is acting as WAN (DHCP)and 2nd NIC acting LAN(static). I am using DHCP to assign IP to eth0 from a Wimax modem. I am also use it as a MAIL server (openmail), and as a DHCP server. My server is of RHEL and kernel version is 2.4.8.18-14 and DHCP client & server version - 30pl1-9. The prolem is whenever I run the command..
ifup eth0
getting the error...
Determining IP information for eth0.../ifup: line277: 23328 Floating point exception/sbin/dhclient ${DHCLIENTARGS} ${DEVICE}
so what should I do?? if I update the DHCP, would it be ok?

This is the first time I post a question on these forums My problem is as follows: I can't start gnome-terminal from the Applications->Accesories menu or from the Alt+F2 application launcher. I get a "Starting Terminal" in the task-bar that disappears after a few seconds and no terminal. I'm pretty sure there is something I did, but I can't really figure out what it is.
The things I've tried so far:
1. I used synaptic to remove and reinstall gnome-terminal. That didn't work
2. Started Xterm and tried to run "gnome-terminal". This is where it gets weird for me:
a. running the command as normal user I get a "Floating point exception" error and obviosly no terminal
b. when I do "sudo gnome-terminal" and enter the root password I get, as expected, a root terminal. I could live with that, but it's not ideal.

I have been trying to convert a DVD9 to DVD5 using the following steps
1)Rip the DVD title(s) to harddisk with DVD:RIP in a project folder. This created VOB files of the the movie and the soundtrack you picked.
2)Concatenate (merge) the VOB files into one by running in a console: cat *.vob > movie.vob
3)demutliplex movie.vob and get the M2V and AC3 files out of there. tcextract -i movie.vob -t vob -x mpeg2 > movie.m2v
4)tcextract -i movie.vob -a 0 -x ac3 -t vob > movie.ac3
5)I then shrank the movie.m2v tcrequant -i movie.m2v -o shrinked.m2v -f 1.5

why installing kde 4.6 from factory repos went wrong ? i used zypper dup with oss, non-oss and update repos for 11.3 to reset to default install and boot went ok :
this goes with the following package versions:
$ kded4 --version
Qt�: 4.6.3
KDE�: 4.4.4 (KDE 4.4.4) "release 3"
i'm using this x86 kernel :
[Code]...
my problem : when i add factory repos (core and extra) for kde install of packages from yast is ok when switching system packages to these. but after reboot i have floating point exceptions and a black screen and can' t boot anymore. the only way out i found so far is to zypper dup to go back to kde 4.4.4

I did a Yum update last Friday. It was done before 5.6 was released so I still have 5.5 + various updates. Yum is now giving me a segmentation fault when I try to run it. I believe it has to do with an improperly synchronized version of sqlite which was updated and then Yum stopped working. I'm guessing that installing the latest Yum RPM will fix the dependency issues. Will this throw me out of sync with for instance updating to 5.6?

I have a centos server running nagios for monitoring. I restarted the machine, it is actually a console server anyway. After getting to the login screen, I typed in my user name but it never propt for my password. I can't even ssh into the system. So I tried to use the installation cd and enter into rescue mode where I typed chroot and was able to enter into the root environment. I was able to configure a network interface in the rescue mode and can ping the machine at this point, though can ssh still. In the root environment, I tried running couple commands. like try to restart the sshd. When I typed /etc/init.d/sshd restart, I got an error saying:
766 segmentation fault.
when I vi any thing I get error:
segmentation fault.
how can I solve this problem? What is causes this. Even in the event of restarting the machine, I see so many fails with segmentation fault.

I have built a CentOS 5.6 kernel with the Preemption Model changed from Voluntary to Preemptible Kernel. Everything works fine except for gdb. When attempting to debug a binary using start or run there is a segmentation fault. If I attach to a running process everything works fine. I expect that I need to make an additional change to the kernel config file, but don't know what it might be. I'm using menuconfig to make the changes: Processor type and features --->Preemption Model ---> [x] Preemptible Kernel (Low-Latency Desktop).
gdb /bin/true
(gdb) run
Starting program: /bin/true
During startup program terminated with signal SIGSEGV, Segmentation Fault.

My centos linux mailserver has crushed and does not allow any login form any user including root. I have managed to start it in single user mode but using vi editor, df command gives segmentation fault. I suspect the /var/* is full but I can neither remove any file/folder/mail/logs nor copy these to make a backup.Attempt to do this as single user/root is met with readonly files yet I have given full permissions to the files and the folders.

On two Centos5 servers, yum gives a segmentation fault error when trying 'yum update' or 'yum check-update' after running 'yum clean' :
[Code]....
The error is the same for the other computer except while attempting to update the rpmforge repository. Nothing has really changed on the servers in some time and 'yum update' worked fine on each yesterday and I have no idea why they would both suddenly fail!

I know it is wrong to use the "==" operator to compare the equality of two floating point numbers. Logically it would seem that if the "==" operator is not usable for floating point comparison, then the "<=" operator would also not be usable. Is this true? The lack of google search results on this topic made me think that it must be true. If that is true, then is it true that the only way to compare floats with <= or >= is with something like the code below? Code: bool smaller_than_or_equal(float a, float b) {
if ( fabs(a-b) < EPSILON){return true;}
else if (a < b) {return true;}
else {return false;}
} I think this is a general question, but if specifics are necessary, I am using the C++ language to code at the moment.

I'm reading a book on assembly, and it talks a bit about the IEEE floating point format.
Quote:
To summarize, the following steps are used to convert a decimal number to IEEE single format: 1. The leading bit of the floating point format is 0 for a positive number and 1 for a negative number. 2. Write the unsigned number in binary. 3. Write the binary number in binary scientific notation f23.f22 ... f0 2^e, where f23 = 1. There are 24 fraction bits, but it is not necessary to write trailing 0's. 4. Add a bias of 127 to the exponent e. This sum, in binary form, is the next 8 bits of the answer, following the sign bit. (Adding a bias is an alternative to storing the exponent as a signed number.) 5. The fraction bits f22f21 ... f0 form the last 23 bits of the floating point number. The leading bit f23 (which is always 1) is dropped.

I put an SD card in a reader, got all the right signs from the kernel (SCSI device: sda; write-through; etc.)including its 2GB size.
When I try to mount /dev/sda1 I get 'floating point exception' as a response, and it won't mount.
I've never had that message returned from mount, and I can't find any reference to it.

One of those odd things I learned the hard way is that if you are writing a shared object (library/.so) and any programs that will link to that library uses floating point numbers, the library must be compiled as if it uses floating point numbers. What that really means is, you need to declare at least one float in the source for the library or when the caller connects and tries to run code in the library, the process aborts.I end up putting a float pi (3.1415); in the code and getting an unused variable warning all the time. There has to be a simpler way, some flag to pass to g++ that says, "include floating point support even if you don't really need to."
p.s. Gosh I hope I remembered this correctly. I encountered this problem doing a multi-platform build for Windows and Linux. This COULD be a VC++ problem that I just carried into Linux by using the same source.

Just updated WinFF to version 1.3.2-1.1. Since then it won't start up any more due to a floating point exeption. System: OpenSUSE 11.4 (x86) + KDE 4.6.0 Debug info:
WARNING] Out of OEM specific VK codes, changing to unassigned
[WARNING] Out of unassigned VK codes, assigning $FF
ERROR in LCL: TLRSObjectReader.SkipValue unknown valuetype
Creating gdb catchable error:
$080D1568
[Code]...
I had the same error with earlier versions of WinFF in earlier versions of OpenSUSE. Then I could fix it by changing the KDE window styles. The error also occurs with the WinFF qt-version.

Over the last few months there have been multiple updates and I am getting a list of things that no longer work or that cause my system to fail. I can no longer open a pdf in firefox. It says there is no application assigned to the task. I ran evince and tried to open a pdf file and received a "floating point" error message on the terminal screen I was working from.
