We use clickhosue version 21.12.2.17 before.It works well

But we found that after upgrade to 22.3.3, the memory of clickhouse used grow up daily .

I don't know if this is a memory overflow

here is the promethues metric 'ClickHouseMetrics_MemoryTracking'  duration last 15days

we have tried  'system drop mark cache '  and change 'max_bytes_before_external_group_by' to '6g'.Not work

Is there anyting else  I can do?
