Issue/Introduction
Customer could not install gateway MPP, because the /var/log volume has run out of space.
Environment
All Supported versions of API Portal
Cause
- Found multiple sendmail and postfix processes.
-
Observed that thousands of files were created under /var/spool/postfix/maildrop, causing the /var volume to fill up.
-
Under /var/log volume, the following files are constantly growing in size.
mail.log
mail.info
daemon.log
syslog
----------
Following message is logged in these files..
"warning - mail_queue_enter: create file maildrop/xx.xx: No space left on device"
Resolution
-
Identified scripts in crontab that runs every second.
-
These scripts were not redirecting their output, resulting in emails being sent to the local root user, thereby flooding the mail queue.
-
Add this to redirect to all the jobs: > /dev/null 2>&1
- Cleanup files in /var/spool/postfix/maildrop manually (rm *).
This stopped the constant update to /var/log system log files.
Now, one can successfully run MPP update.
