Kernel: Event buffer is too long. Any new events are NOT being logged!

Issue

Sometimes you may see the following entries in the /var/log/messages:

Feb 28 13:07:15 jp74 kernel: Event buffer is too long. Any new events are NOT being logged! (events_in_buffer(500000) >= max_events(500000)

1. Check the status of the cloudlinux-file-change-collector service:

systemctl status cloudlinux-file-change-collector

2. If it's down, recreate the database:

mv /var/lve/cloudlinux-fchange.db /var/lve/cloudlinux-fchange.db.broken

3. And start it:

systemctl start cloudlinux-file-change-collector

4. It should work fine now!
