周沛辰 commented on IOTDB-5527:
----------------------------
OOM occurs during system operation, and there are inner space compaction and
query at the same time, but no cross space compaction, so it is difficult to
accurately locate the OOM problem caused by compaction. In addition, after the
system restarts and recovers from OOM, the recover process of compaction
reports an exception. This problem has been fixed in 0.13.4. See IOTDB-5286.

> Issue Type: Bug
> Reporter: 周沛辰
> Assignee: 周沛辰
> Priority: Major
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Find a scenario where the 0.13.4 compaction will lead to memory OOM: the test
> environment for importing historical data, the JVM memory of about 10G, the
> write throughput is relatively high, and the out-of-order ratio is not low.
> After using this data to start in a small memory environment, it will
> directly OOM.
