Please go to Admin > System Settings > Performance Settings > Backend Cache tab and send me a screenshot of what you have set there.

Additionally, it looks like your backendcache tmpfs is full:

Code: Select all

tmpfs                       512M  512M     0 100% /usr/local/nagiosxi/tmp/backendcache

Please run this command:

Code: Select all

mount -t tmpfs -o size=1g tmpfs /usr/local/nagiosxi/tmp/backendcache

Then Apply Configuration through the web interface and then attach a FRESH copy of your profile once that's completed.

Then validate to see if your issue is resolved, if it's still not resolved, try running these commands:

Code: Select all

systemctl stop crond
systemctl stop npcd
systemctl stop nagios
systemctl stop ndo2db
pkill -9 -u nagios
for i in $(ipcs -q | grep nagios |awk '{print $2}'); do ipcrm -q $i; done
rm -rf /usr/local/nagiosxi/var/dbmaint.lock
rm -rf /usr/local/nagiosxi/var/event_handler.lock
rm -rf /usr/local/nagiosxi/scripts/reconfigure_nagios.lock
systemctl restart mysqld || systemctl restart mariadb
systemctl start ndo2db
systemctl start nagios
systemctl start npcd
systemctl start crond
systemctl restart httpd
