Programming :: Process Abruptly Ends Without Any Error Or Dump?
Apr 21, 2010
I have a process which runs for a while and then due to some unknown reason ends abruptly without giving a core. I tried looking in the logs and after watching for a pattern am still not 100% sure of the reason. So I was wondering if there is a way to catch the signal which ends the process and print some values in the handler function. I have called the handler for SIGTERM and SIGABRT functions but none of these are getting triggered. I looked online and did not find any other option. Can you please suggest if tehre is any other signal that can be caught for this unknown abrupt termination.

I have used Dump Command to dump the application files. For Full backup the level 0 is working fine. For incremental backup I used the level 1 or 2 it is getting the error as
DUMP: Only level 0 dumps are allowed on a subdirectory
DUMP: The ENTIRE dump is aborted.
The code I used
===============================
#!/bin/bash
#Full Day Backup Script
#application folders backup
#test is the username
now=$(date +"%d-%m-%Y")

I have a doubt about signals in C programming. I have done this little program to explain it. It creates a child process with fork and, when the child ends, receives the SIGCHLD signal and wait for its termination.Ok, quite easy, BUT when I execute this code the SIGCHLD signal is received twice, first as an error (returns -1) and the second one to finish the child process.I don't understand the meaning of the first received signal. Why is it generated? Is the code wrong? (if you add the SIGINT and press Ctrl+C during the execution it also receives two signals instead of one)
Code: #include <stdio.h>
#include <unistd.h>
#include <string.h>

I want to generate core dump files from my program when it crashes. Its a pretty big process and has about 10-11 threads in it.I have followed the documentation to enable core dump by setting ulimit to unlimited etc. I quickly tried "A demo program creating a core dump" from the following webpage, which succeeds in Segfault and dumping a core file in the directory that I configured.However, I tried running my original program and caused it to crash. I did this by making calls to kill(), raise() or the same null pointer access as shown in the webpage above. In each case, my program crashed but did not generate a core dump file. Am I missing something?My program is in C++ and my environment is Redhat 9.0 (kernel 2.4.20)
Going through the "Why do I NOT get a core dump?" section on the same webpage as above, I can see two potential problems. One - there are issues with the suid/sgid (bullet # 6). I am not able to change any settings with suid because my system does not contain either /proc/sys/fs/suid_dumpable or /proc/sys/kernel/suid_dumpableTwo, my program has threads in it and the bullet # 8 is the problem.

In my program, I fork() to get a child process. Because of some problem, child process terminates by a segmentation fault. Parent process is still running. I have compiled my code with -g option. I have done: ulimit -c unlimited. I am not getting core dump of the child process. How can I get the core dump of child process?

This is opensuse 11.2.
Somehow zypper is running at 100% cpu and won't die with command line kill, the system monitor kill, terminate or anything. I set it's priority to the lowest it will go, tried to stop it then kill it, nothing works as it simply is not responding to anything and it has been running now for 47 hours.
Is there a way to simply dump a process out of memory without requiring it to respond to a signal? because signals are doing nothing.

I'm writing a sort of toy shell using fork() and execv(). It runs smoothly enough untill the user enters an invalid command at which point the program hangs, so I need a way to check if the program loaded using execv returned correclty or not in the parent process and kill it if it didntI tried writing stderr to a text file to see if something whent wrong but doesnt really work out. Try running ./digenv GDM -i -Q for instance. (-Q is an invalid option for grep which the program runs at a certain point).Heres the code:

When running the script i get the following error message:

I am developing an application whose executable is generated inside a certain folder hierarchy (say: /DevPath/MyProject/bin). My source code is located in a different branch of this hierarchy (say: /DevPath/MyProject/src). When my app crashes, its core files are stored in /DevPath/MyProject. I'm developing the app on a pc, but running it on a separate platform in which i can only execute it. Folder hierarchy is the same as above on both computers. Usually, when a new executable version is ready, we update both the executable and the source code on the target platform, transferring all the new /DevPath/MyProject folder on it. But sometimes it can really be a bother, so we update only the executable.
1)In the case we only update the executable, keeping an old source code version, and the app generates a core file, can i trust the backtrace produced by gdb in this case? I.e., does gdb need the latest source code files or it just needs the debugging information?
2) (More radical question ) Do i really need to keep the source code on the target platform for core dump analysis or i just need the executable?

In one of our core dump we have the followings in the core back trace:
#0 0xb77bf947 in raise () from /lib/tls/libc.so.6
#1 0xb77c10c9 in abort () from /lib/tls/libc.so.6
#2 0xb77f56ba in __fsetlocking () from /lib/tls/libc.so.6
#3 0xb77fcf7f in mallopt () from /lib/tls/libc.so.6
#4 0xb77fd022 in free () from /lib/tls/libc.so.6
It occurred in a memory block free operation. From our analysis, there seems no issue relate the the memory block it self. The memory pointer pointed to the right memory block to be freed and the contents of the memory seems right (not corrupted), in one world, there is nothing obviously wrong. Does any one have any ideas what could be wrong when seeing about?

I'm trying to write a C program that extends an array to any user inputed size.
Code:
if (arraysize == 0) {
arraysize = (int) pos + 1;
a = (int *) calloc (arraysize,sizeof(int));
for (i = 0 ; i < arraysize ; i++ )
a[i] = -1;
code....
The program dumps with that sequence of inputs everytime, but might dump an input before or after if different positions are requested. Interestingly, when I tested pos = 2000..2008, I got no dumps. So is realloc somehow trying to extend the array into bad space?

To analyse a coredump, I need to specify program name/path in GDB/KDevelop. Since the program name along with arguments is also within a core dump, I wonder if it doesn't keep the proper path of program that crashed and so asks for it?

I am trying to port some "C" code from Solaris to Linux. I have a Dell PowerEdge R610 with an Intel Xeon E5504 quad core processor running Red Hat Linux Enterprise 5.3. I am compiling in 64 bit mode. I have managed to get the code compiled and linked, but when I attempt to execute it, I get a core dump in one of the C library calls (like strcpy or printf.)
I have a static library that contains our own code that makes the call to the C library. If I move the library method into the source file with the main method and rename it to be certain that I am executing my method instead of the method in our library, the call succeeds. Eventually another static library call is made that results in a core dump in the shared object. I compile my library code into a static library with gcc as:

When issueing a "mkfifo /tmp/1"on my laptop(x86), I get this file:
Code: prw-r--r-- 1 root root 0 2011-04-11 15:09 1
If I issue the same command on a AT91SAM9260(arm), I get this file:

What could I be doing wrong, since I am getting a pipe "|" in the end of the filename?

For one of the users on my system, knetworkmanager abruptly ceases to autostart once on a while. This happens once in roughly 10-15 days. When that happens, i have to go into .kde4/share/config/networkmanagementrc and manually toggle Autostart=true (from false). This trick works for another 2 weeks or so, before the value of "Autostart" automagically changes to 'false' and i have change it again.I dont mind doing it manually, but the user in question is my mom, and she does not have the know-how to do it herself when i'm not around.

I have an 9.04 installation of Ubuntu.After a classical system update via the GNome-GUI my computer (laptop ASUS PRO55series) got the sick habit to turn off abruptly during work.It's like if there were no electricity in my house.It is not the hardware since I also have windows vista and it works fine.I suppose this is from ubuntu; it could be from the heat regulation, that ubuntu thinks it is too hot inthere and just turns off the laptop.

I use ubuntu 9.10 karmic koala as my desktop OS. My internet connection is creating problems these days, ever since I started downloading torrents for iso files. Whenever the downloads in transmission client is running, the internet gets disconnected abruptly, and even my other downloads in d4x stops. On using the plog command in the terminal, it shows the following:
Sep 5 03:32:57 gunjan pppd[3241]: LCP terminated by peer
Sep 5 03:32:57 gunjan pppd[3241]: Connect time 4.5 minutes.
Sep 5 03:32:57 gunjan pppd[3241]: Sent 2102494 bytes, received 31842568 bytes.
Sep 5 03:33:00 gunjan pppd[3241]: Connection terminated.
Sep 5 03:33:00 gunjan pppd[3241]: Modem hangup

Sep 5 03:35:10 gunjan pppd[3241]: Timeout waiting for PADO packets
Sep 5 03:35:10 gunjan pppd[3241]: Unable to complete PPPoE Discovery
I dont understand much of it, as am a new user using linux systems from only a few months ago, can't find out. Also on closing the transmission client the other downloads in d4x run perfectly well and so does my internet connection.
