Hi Shashank,<br>
Try setting core size to big value, typically its 0.<br>
<br>
# ulimit -a<br>
core file size (blocks, -c) 0<br>
<br>
shows you limits of various size. You can set core<br>
file size using<br>
<br>
#ulimit -c 999999999999<br>
<br>
and using the same shell start oned and then try to<br>
generate the core dump.<br>
<br>
Hope this helps.<br>
<br>
Thanks and Regards,<br>
Manish<br>

Hi<br>
<br>
I have set ONE_MAD_DEBUG=1 in /etc/one/defaultrc and started<br>
opennebula. After that, I have sent SIGQUIT ( kill -3 ) to oned<br>
process. I couldn't see any core dump generated. I have compiled<br>
opennebula from source on x86_64 arch but it has crashed a couple of<br>
times yesterday with the following messages in syslog:<br>
<br>

I have checked out "general protection fault" on wiki (<br>
<a href="http://en.wikipedia.org/wiki/General_protection_fault" target="_blank">http://en.wikipedia.org/wiki/General_protection_fault</a> ). However, I am<br>
not able to determine if is a problem with selinux ( apparmor on ubuntu<br>
) or an issue with 64 bit architecture. Hence, I was testing the core<br>
dump functionality in order to ensure that the dump gets created when it<br>
actually crashes. Please let me know if I am missing anything here.<br>
