Add --max-old-space-size=1024 to the node process running the Next.js
server. This caps V8's old-generation heap at 1024MB, forcing the
garbage collector to run more aggressively as memory usage approaches
the limit.
Previously, users saw Next.js RSS grow to 4GB+. This was caused by a
reference chain that prevented GC from freeing memory:
AfterContext (vercel/next.js#89091) retained ServerResponse objects
after client disconnect, which held zlib Transform streams (from
compress: true), which allocated native C++ buffers outside V8's
heap entirely — invisible to GC and uncapped by --max-old-space-size.
Combined with the prior commit's fixes (compress: false moves gzip to
nginx, httpBatchLink closes connections faster, socket-cleanup.cjs
destroys zombie CLOSE_WAIT sockets every 60s), GC can now actually
reclaim memory because:
- zlib native buffers no longer exist (compress: false)
- The AfterContext → ServerResponse reference chain is broken by
socket cleanup destroying the underlying sockets
- The JS heap is capped at 1024MB so V8 GCs more frequently for
the memory it does control
Also fixes the Dockerfile to copy socket-cleanup.cjs from the builder
stage instead of the host context.

Addresses high memory usage by adding gzip compression to nginx (removing it from nextjs)
socket cleanup handling, and tRPC client optimizations.
