All errors report \"end of input\" at the same second as \"14794048 buffers freed\".\n\n**Root cause:** `http.Server.ReadTimeout = 20s` (`cmd/cc-backend/server.go:347`) sets a hard deadline on the TCP connection from acceptance time. The `/api/write` handler streams `r.Body` line-by-line via `lineprotocol.NewDecoder(r.Body)`, interleaving reads with `WriteToLevel()` calls. During retention, `freeAndCheckEmpty()` holds `root.lock.Lock()` while recursively freeing the entire tree (14M buffers). Every `DecodeLine` iteration blocks on `root.lock.RLock()` in `findLevelOrCreate`. Once 20 seconds elapse, the conn read deadline fires and `r.Body.Read()` returns a deadline error — the decoder reports \"end of input\" mid-parse.\n\n**Why `WriteTimeout` is not a concern here:** `WriteTimeout` only sets `net.Conn.SetWriteDeadline()` — it does not affect `Read()` on the body. If the handler takes >20s, the response write may fail (client sees broken connection), but all data that was decoded was already written to the store. No messages are lost.\n\n## Fix — `cmd/cc-backend/server.go`\n\nReplace `ReadTimeout` with `ReadHeaderTimeout`. Per Go docs, `ReadTimeout` covers the *entire* request including body — inappropriate for endpoints receiving large streaming batches. `ReadHeaderTimeout` only limits header reading (slowloris protection) while allowing body reads to block indefinitely on lock contention without truncation.\n\n### Changes\n\n1. Rename constant: `defaultReadTimeout` → `defaultReadHeaderTimeout`\n2. Rename variable: `readTimeout` → `readHeaderTimeout`\n3. Change `http.Server` field: `ReadTimeout` → `ReadHeaderTimeout`\n\n```go\nconst (\n\tdefaultReadHeaderTimeout = 20\n\tdefaultWriteTimeout = 20\n)\n\nfunc (s *Server) Start(ctx context.Context) error {\n\treadHeaderTimeout := time.Duration(defaultReadHeaderTimeout) * time.Second\n\twriteTimeout := time.Duration(defaultWriteTimeout) * time.Second\n\n\ts.server = &http.Server{\n\t\tReadHeaderTimeout: readHeaderTimeout,\n\t\tWriteTimeout: writeTimeout,\n\t\tHandler: s.router,\n\t\tAddr: config.Keys.Addr,\n\t}\n```\n\n### Why this is sufficient\n\nWith `ReadHeaderTimeout` instead of `ReadTimeout`:\n- **Body reads have no deadline.** Even if `DecodeLine` blocks for minutes on the root lock held by `Free()`, the body stream stays open. No truncation, no dropped messages.\n- **Header timeout still protects** against slowloris (slow-header) attacks.\n- **`WriteTimeout` is orthogonal** — it only affects writing the response. Worst case: client gets a connection error after data was already processed. This is the same behavior as any other slow handler and does not cause data loss.\n\n## Files to modify\n\n- `cmd/cc-backend/server.go` — lines 347–358\n\n## Verification\n\n- `go build ./cmd/cc-backend/...`\n- `go vet ./cmd/cc-backend/...`\n\n\nIf you need specific details from before exiting plan mode (like exact code snippets, error messages, or content you generated), read the full transcript at: /Users/jan/.claude/projects/-Users-jan-prg-ClusterCockpit-cc-backend/b843de8b-f396-4eb0-83ba-fb654a2b4072.jsonl"},"uuid":"46890d23-3008-48c6-8d91-7f5a5133fdea","timestamp":"2026-03-23T06:04:14.916Z","planContent":"# Fix: Line Protocol Parse Errors During Retention\n\n## Context\n\nDuring retention (`Free()` freeing 14M+ buffers), concurrent `/api/write` requests fail with truncated line protocol errors like `expected '=' after tag key \"hostna\"`.
