What's Wrong?

I was working on a plan for about 30 minutes and my RAM usage was 10gig. Earlier, today it was high enough to freeze up my MAC Studio computer. I was running a test suite at the time and had been writing tests.

Claude Code 2.1.117.

What Should Happen?

It should run without hogging all the RAM.

TL;DR

The issue can likely be mitigated by optimizing memory usage or identifying a memory leak in the Claude Code version 2.1.117.

Guidance

  • Investigate the test suite and plan creation process to identify potential memory-intensive operations that could be causing the high RAM usage.
  • Consider reducing the scope or complexity of the plan and test suite to see if it alleviates the memory issue.
  • Since this is reported as a regression, comparing the current version (2.1.117) with the previous working version might help identify changes that could be contributing to the memory issue.

Notes

The lack of specific error messages or logs limits the ability to provide a precise fix. The issue might be related to how Claude Code handles memory, especially during test suite execution and plan creation.

Recommendation

Apply workaround: Given the information, a workaround such as optimizing the test suite or reducing plan complexity might be necessary until a more permanent fix can be identified and implemented.
