### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Description Currently, the mem tracker uses the tcmalloc hook and the tcmalloc property `generic.total_physical_bytes` to limit process memory usage. Both 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. ### Solution _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
