> Key: HDDS-13400
> URL: https://issues.apache.org/jira/browse/HDDS-13400
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Client, s3gateway
> Reporter: Sammi Chen
> Priority: Major
>
> The issue is reported by Hao Guo.
> Currently RpcClient has a ElasticByteBufferPool to reuse buffers during EC
> data read and write. ElasticByteBufferPool can save the time of buffer
> allocation. While this Pool doesn't have a upper limit, so in s3g case, a
> long lived RpcClient will accumulate all buffers allocated through this pool,
> which lead to high memory pressure of s3g.
