Fix buddy cache evicting chunks with live buffers by franz1981 · Pull Request #17154 · netty/netty · GitHub

Motivation:

The shared ConcurrentSkipListChunkCache eviction policy picked the chunk with the lowest refCnt when the cache exceeded CHUNK_REUSE_QUEUE. Since chunks enter the cache with refCnt = 1 + N (N live buffers), evicting them creates zombie chunks: out of the cache, backing buffer still alive until all N buffers release. This caused 16 GB RSS on the AG benchmark.

Modification:

Only evict chunks where refCnt == 1 (no live buffers — just the base construction reference). If no idle chunk exists, let the cache grow past the cap. markToDeallocate on an idle chunk decrements refCnt to 0, triggering deallocate which frees the backing buffer cleanly.

Result:

Less memory churn under allocation pressure still allowing it to shrink on subsequence cache requests
