   This issue might be a duplicate of existing issues. Please check:

   • Memory Megathread #20695: Memory Megathread — the central tracking issue for memory/resource usage problems in OpenCode. The maintainers are actively collecting heap snapshots there to diagnose these issues.
   • 1.4.0 memory leak. Bun occupies more than 3g memory at most. #21430: Bun occupies excessive memory on Windows (similar symptoms on Windows 11)
   • Memory leak: SSE connections stuck in CLOSE_WAIT cause unbounded AsyncQueue growth (~14 MB/sec) #22198: SSE connections causing unbounded memory growth (~14 MB/sec)
   • High memory usage: Bun's SQLite maps entire DB file into process address space via mmap #22429: High memory usage from Bun's SQLite mmap behavior

   If your issue is specifically about memory/CPU resource consumption, contributing a heap snapshot to #20695 would be especially helpful to the maintainers.
