The D drive runs out of space after two CLI windows are launched.

[frith5308-glitch]

At first, when I used Nexus-cli, I always ran two CLIs simultaneously and never encountered any issues, except that the accuracy rate of the tasks was slightly affected. After I updated to Nexus CLI v0.10.11, I ran two CLIs with the following command parameters: 
                                  nexus-network start --node-id ******** --max-threads 4 --max-difficulty smal.
 I carefully monitored the task execution, and found that the speed and accuracy rate of the new version of the CLI had both improved. After running for 9 hours, I noticed that both CLIs stopped working, and the page displayed "PS D:>". My WSL is installed on the D drive, and it showed that the D drive was out of space.
Later, someone told me to uninstall WSL. After I did that, the disk space became available again.

Could anyone tell me what exactly is causing my disk space to run out?

I'm not sure, but you could check the size of the .nexus directory in your home directory to see if it's Nexus related. Try "du -h"
