tailing-sidecar container gets ContainerOOMKilled, memory leak? #664

Seeing memory consumption grow periodically and then the container gets OOMKilled. Memory leak in the tailing agent container needs profiling(not the operator). Same pattern repeats every 10 days. Attached is the image showing memory usage.

Following are the version details: tailing-agent public.ecr.aws/sumologic/tailing-sidecar:0.9.0

Do you observe this issue for the latest release https://github.com/SumoLogic/tailing-sidecar/releases/tag/v0.11.0? In latest release there is following change which impacts tailing-sidecar image:

build(deps): bump Fluent Bit from 2.2.2 to 3.0.0 https://github.com/SumoLogic/tailing-sidecar/pull/672

In the future we plan to switch to otelcol based tailing sidecar at this moment there are only dev container images https://github.com/SumoLogic/tailing-sidecar/pkgs/container/tailing-sidecar-otel
