Did this start happening recently or after an upgrade? Or something else?
Could you PM me your profile?
To get the Nagios XI Profile --> On the XI Home Page click "Admin" > "System Profile" --> "Download Profile" button
Save the profile.zip file and upload it here or PM me.
If you receive a PROFILE BUILD FAILED
Please follow this article,
may take me a bit of time to try the command as the issue was not the sudoer permissions per the article and has now junked out my sudoers file
>>> /etc/sudoers: Alias "NAGIOSXI" already defined near line 114 <<<
>>> /etc/sudoers: Alias "NAGIOSXIWEB" already defined near line 115 <<<
sudo: parse error in /etc/sudoers near line 114

In the early release of 5.4.11, there was a packaging error.
The way to fix this is to redownload the latest tar release of 5.4.11 and run ./upgrade
Let me know if when you installed/upgraded to 5.4.11.
That sounds about right, and since the error is still in your event_handler.log, could you try doing a ./upgrade with the latest 5.4.11 tar to see if that clears it up?
You can run these commands through the terminal of your XI Server. (They are separate commands)
You should save a backup just in case. (There's a link in the documentation)
