Core Dump fault virtual address on DragonFly v2.13.0.154.g481b38-DEVELOPMENT

[Siju George]

Hi,

I didn't receive any response to the core dump message i sent yesterday.
Should i be sending these messages to bugs instead? please let me know.

I have put the coredump at leaf:/home/sgeorge/crash/Coredump20111115.tbz
My kernel version is DragonFly v2.13.0.154.g481b38-DEVELOPMENT
These Core dumps does not happen every time.
Now I have removed a 512 MB RAM from the machine and I have got the
system up now and I am upgrading to the latest src.

Thanks
