The service will not be restarted.' — tsserver OOM at 3072 MB default or a TS serve… ## Body Cause (Documented platform behavior): Client restarts tsserver up to 5 times; >5 restarts within 10 seconds sets 'fatally crashed' and stops restarting; within 5 minutes shows a warning. Memory is capped by --max-old-space-size from js/ts.tsserver.maxMemory (default 3072, min 128); >4 GB requires a custom Node via js/ts.tsserver.node.path. Fix status: documented_behavior Limitations: - Strings read from VS Code main-branch source at the pinned SHA; shipped builds may lag. - OOM as the crash cause is inferred from the memory settings; the crash message itself does not state the reason. - Not reproduced in this session. Other error fragments: - The JS/TS language service immediately crashed 5 times. The service will not be restarted. - This may be caused by a plugin contributed by one of these extensions: Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/microsoft/vscode/7fbceca31b927645eda89716dfa3459f2c938d78/extensions/typescript-language-features/src/typescriptServiceClient.ts (official_docs, 2026-09-27, documented_behavior): typescriptServiceClient.ts: after >5 restarts within 10 s shows 'immediately crashed 5 times.
