Issue:
Utility (compress) scripts did not work. Run out of disk space.
Log message:
zip I/O error: No space left on device
Troubleshoot:
From crontab log, zip error messages were logged. They identified that the host run out of inodes and caused gzip cannot compress archived files (CDR files, reprots, etc.). Then it run out of disk space.
Solution:
Delete some old files manually, then the utility scripts should work again.
