claude-code - 💡(How to fix) Fix [Bug] Anthropic API: Excessive token consumption on initial prompt and simple continuations [1 participants]

[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/kt/.local/share/claude/versions/2.1.126 (expected in multi-process scenarios)\n at r86 (/$bunfs/root/src/entrypoints/cli.js:2768:2177)\n at HD8 (/$bunfs/root/src/entrypoints/cli.js:2768:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-05-04T21:29:24.122Z"}]

TL;DR

Investigate the lock acquisition failure error to address the potential resource leakage causing high usage percentages.

Guidance

• Review the error message indicating a "Lock acquisition failed" error, which might be related to the high usage percentages.
• Check the file path /Users/kt/.local/share/claude/versions/2.1.126 for any locking issues or permission problems.
• Consider the "multi-process scenarios" hint in the error message, which could imply a concurrency issue.
• Verify if the problem persists across different sessions or terminals to isolate the cause.

Example

No code snippet is provided as the issue does not imply a specific code-related fix.

Notes

The provided information suggests a potential issue with resource management or concurrency, but more details about the application's behavior and the Opus 4.7 service might be necessary for a comprehensive solution.

Recommendation

Apply workaround: Investigate and resolve the lock acquisition failure to mitigate the potential leakage, as upgrading to a fixed version is not explicitly implied in the given information.
