Possible Cause

Check whether a large amount of data is saved in /tmp.

Solution

1. Go to the Terminal page. In the /tmp directory, run the du -sh * command to check the space usage of the directory.

   sh-4.3$cd /tmp
   sh-4.3$du -sh *
   4.0K    core-js-banners
   0       npm-19-41ed4c62
   6.7M    v8-compile-cache-1000

2. Delete unnecessary large files.
   1. Delete the sample file test.txt: rm -f /home/ma-user/work/data/test.txt
   2. Delete the sample folder data: rm -rf /home/ma-user/work/data/
