Understanding high memory usage of otel grpc collector

[shravani154]

Hello team. I'm currently utilizing Otel Java Agent version 1.30.0 with a gRPC collector for trace collection. At the moment, I'm not exporting metrics and logs. However, I've observed a gradual increase in memory usage by the Otel collector, starting at 400MB and gradually reaching up to 1300MB or more, without any reduction. I'm interested in finding solutions to address this issue.

Ensure you are not creating grpc connection frequently for every event as grpc connections are meant to keep longlive connection by design.

So we need best practice configuration for grpc connection and package handling
