Thanks for your quick response.
cat /proc/iomem | grep "System RAM"
00000000-0009fbff : System RAM ----> 638kB
00100000-fbfeffff : System RAM ----> 4127679kB
Total : 4127679 + 638 = 4128317kB --> 4031.56MB
4031.56MB - 64MB = 3967.56MB
/proc/vmcore size ---> 4166476832 bytes ---> 3.88GB --> 3,973.12MB
(Dump-Capture kernel)
Conclusion:- vmcore size is approximately 6MB greater than the SYSTEM RAM size
Thanks
