What's Wrong?

After leaving a Claude Code session open overnight and putting the laptop into sleep mode, I discovered that the session had consumed 760GB of disk space and approximately 15GB of memory by the morning. The terminal remained open but the system was nearly unresponsive due to the extreme disk and memory pressure.

What Should Happen?

Claude Code should remain idle or enter a suspended state without continuous resource consumption during system sleep.

Additional Information

I used git bash as a terminal, also I have generated a heap dump using /heapdump which is available upon request for the engineering team. I had to manually clear the storage to regain control of my machine.

The huge file was stored under: %TEMP%\claude\<File-Path>\c9943489-d117-4eef-ae91-59785be1ed40\tasks\bpjcyiac0.output
