# Proposed changes
Issue Number: close #xxx
## Problem summary
After the query ends, inaccurate query mem tracker in tpch : Q1, Q6, Q13
|tpch|old query mem tracker|fix query mem tracker|
|--|--|--|
|Q1|-300M|178.34M|
|Q6|-100M|13.56M|
|Q13|-2G|4.75G|
The reason for the negative number is that a lot of memory is freed after
the query mem tracker is destructed.
Q13 minimal case:
```
-2G
select
count(o_orderkey) as c_count
from
orders right outer join customer on
c_custkey = o_custkey
and o_comment not like '%special%requests%';
```
