Description Daniel Tröder

2020-09-24 11:02:35 CEST

The cron job /etc/cron.daily/univention-spamassassin can fail and send an email if sa-learn cannot find a file.
That happens, because univention-sa-learn starts sa-learn with a list of files to scan. But those files can disappear (renamed/moved) in the time between starting sa-learn and it scanning them.
The cron jobn then fails and sends an email:
-----------------------------------------------------------------
Cron <root@ucs04> test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )  /etc/cron.daily/univention-spamassassin:
find: '/var/spool/dovecot/private/DOMAIN/USER/Maildir/cur/1597119.......,S': No such file or directory
run-parts: /etc/cron.daily/univention-spamassassin exited with return code 1
-----------------------------------------------------------------

Modify univention-sa-learn to start sa-learn with a list of directories and not files.

When at it, start sa-learn with a low I/O priority, for example: "ionice -c3".
