Severity: 3-Major


In the /root directory, there is a file named 'dead.letter' containing the following: /etc/cron.daily/cleanup_sync_files: ls: cannot access /config/filestore/sync_file_request_d: No such file or directory.


The file /root/dead.letter grows daily by 5 lines regarding missing sync_file_request_d directory.


cron is running.


To avoid output that triggers mail to the dead.mail file, do the following: add '2> /dev/null' to the crontab daily script: /etc/cron.daily/cleanup_sync_files - for file in `ls $path` + for file in `ls $path 2>/dev/null` # <-- the 2>/dev/null

Fix Information

The 'dead.letter' is no longer generated.
