Thank you for some log files.
vmcore-d30.log:
open("/proc/vmcore", O_RDONLY) = 4
[snip]
lseek(4, 2885288664, SEEK_SET) = -1 EINVAL (Invalid argument)
Your system has 4GB memory, and /proc/vmcore size is almost 4GB, right ?
If yes, the above lseek() should *not* fail because the offset (almost 2.7GB)
is in /proc/vmcore. So I guess that this problem is due to a kernel.
Please try copying /proc/vmcore by `cp` command, and check whether the
size of copied file is the same as /proc/vmcore.
Thanks
