    Description

      Running scale test of connected 10K instances, we end up consuming 1.2GB heap, which boils down to around ~125kB per session overhead.

      Drilling down into this, it looks like we are retaining a 32KiB HeapByteBuffer in each session – i.e. 25%, through a read timeout task. Investigate the root cause for this, potentially switching to netty provider instead of nio2.
