# Proposed changes Issue Number: close #10923 ## Problem Summary: ### solution Limit process memory usage using the actual physical memory of the process in `/proc/self/status`. This is independent of the consumption value of the mem tracker, which counts the virtual memory of the process malloc. ### motivation Currently, the mem tracker uses the tcmalloc hook and the tcmalloc property `generic.total_physical_bytes` to limit process memory usage. Both the tcmalloc hook and `generic.total_physical_bytes` record the total length of virtual memory of the process malloc, not the physical memory actually used by the process in the OS. When there is a large amount of memory that is not used after application (this is abnormal code), the virtual memory of the process will be much larger than the physical memory actually used by the process, causing the mem tracker to limit the memory too strictly. ## Checklist(Required) 1.
