Guide on managing, debugging, and analyzing process memory in Cisco routers, enhancing system performance and troubleshooting efficiency.
This module describes memory management processes.
In Cisco IOS XR routers, process memory management refers to the efficient allocation and isolation of memory for individual processes within the modular operating system. Each process runs in its own protected memory space to ensure stability and prevent interference.
IOS XR routers has dynamic memory allocation, leveraging segments like code, data, stack, heap, and shared memory for process execution.
Starting with Cisco IOS XR Release 26.2.2, PAM is disabled in the 64-bit ARM architecture (8000-aarch64). As a result, the memory monitoring commands including show memory-snapshots, show memory-top-consumers, show memory-delta, and so on are not supported and do not display any output.
