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
