On a system with 1 TB of total physical memory installed, this means 224 MB (160 MB + 64 MB). For example, on the x86_64 architecture, the amount of reserved memory is 160 MB + 2 bits for every 4 KB of RAM. To find out the exact name of the machine architecture (such as x86_64) and print it to standard output, type the following command at a shell prompt:Īnother factor which influences the amount of memory to be reserved is the total amount of installed system memory. One of the major factors is the system’s hardware architecture. The memory requirements vary based on certain system parameters. When reserved, this part of the system memory is not available to main kernel. In order for kdump to be able to capture a kernel crash dump and save it for further analysis, a part of the system memory has to be permanently reserved for the capture kernel.
