Symptoms

Anacron job 'cron.daily'

ls: cannot open directory /usr/lib64/httpd/modules: Permission denied
failed to open semaphore file /usr/local/psa/var/utilities.sem: Permission denied
System error 13: Permission denied
Cause
Product issue:
-
#PPPM-12853 "In Plesk Obsidian 18.0.34 and later, the Plesk administrator no longer receives daily emails from the Plesk cron task notifying that “ls: cannot open directory /usr/lib64/httpd/modules”."
Fixed in:- Plesk Obsidian 25 March 2021 (Linux)
- Plesk Obsidian 23 March 2021 (Linux)
Resolution
Please consider updating your server:
Workaround
Workaround I
- Log in to Plesk via SSH
-
Disable SELinux
# setenforce 0
Workaround II
Ignore the notifications from Logrotate. A feature implemented in the update 34 will not be available:
- Apache graceful restart is now more stable and less likely to break Apache during log rotation.
