gemini-cli - 💡(How to fix) Fix previous session crashed due to heap memory [1 comments, 2 participants]

What happened?

I asked Gemini to look at a CSV and count the unique email addresses. The CSV was only 168 KB, but resulted in high memory and heap crash below. I previously pasted the csv contents into the Gemini console and it began running sluggishly (never returned correctly). So the 2nd request to read the CSV file may not have been the only trigger.

High memory usage detected: 13.42 GB. If you experience a crash, please file a bug report by running /bug
