extent analysis

TL;DR

The issue is likely due to a memory leak in Claude Code, causing it to consume excessive RAM even when idle, and a workaround or fix may be necessary to prevent this behavior.

Guidance

  • Investigate the Claude Code version 2.1.107 for known issues or memory leaks, as this version is reported to have the problem.
  • Monitor the system's memory usage while running Claude Code to identify any patterns or spikes in memory consumption.
  • Consider reaching out to the Anthropic API or Claude Code support team for guidance on optimizing memory usage or reporting the issue.
  • If possible, try running Claude Code on a different platform or operating system to see if the issue is specific to Ubuntu/Debian Linux.

Example

No code snippet is provided as the issue does not contain specific code-related information.

Notes

The issue lacks detailed error messages or logs, which could provide more insight into the cause of the memory leak. Additionally, the fact that this is not a regression and has never worked as expected suggests a potential underlying issue with the Claude Code version or configuration.

Recommendation

Apply workaround: The best course of action is to apply a workaround, such as monitoring and limiting memory usage, until a fix is available or the issue can be further investigated.
