# Proposed changes
Issue Number: close #xxx
## Problem summary
1. When Doris BE is deployed with Hadoop, there is an OOM risk in only using
BE process memory control limit at present, and additionally use `/proc/meminfo
MemAvailable` to control memory;
2. Optimize the log printing of MemTracker, and fix the bug that Jemalloc
does not print the log when the process memory exceeds the limit.
3. Print query peak mem usage in `fe.audit.log`.
