Memory Mapping Description The pmap command reports the memory map of a process or processes. On comparing the output of pmap over time, I see multiple anon blocks getting added either at the top of heap or between two native libraries. Options The following options are supported: -a Prints anonymous and swap reservations for shared mappings. -F Force. The pmap Utility Finding the Process ID Using pmap The Extended Display Show Me Everything Memory Management is Complicated Finding out how much RAM a Linux process uses isn&#39;t a simple matter&#8212;especially when shared memory needs to be considered. As such, they have nothing to do with the Java heap (other than the fact that the entire heap should be stored in just such a block). Thankfully, the pmap command helps you make sense of it all.
