If your kernel message queue is filling up, you are probably running an older version of NDO: /usr/local/nagios/bin/ndo2db --version root@fe1.nagios (Linux) $ /usr/local/nagios/bin/ndo2db --version NDO2DB 2.0.0 Copyright (c) 2009 Nagios Core Development Team and Community Contributors Copyright (c)...

After doing some more digging on the box, we're seeing what appears to be an ndo2db issue: I see this in the logs: Oct 4 07:18:59 fe1 ndo2db: Warning: queue send error, retrying... Oct 4 07:19:00 fe1 ndo2db: Message sent to queue. Oct 4 07:19:00 fe1 ndo2db: Warning: queue send error, retrying... Oct...

Looks like your DB is offloaded, and I believe this issue could be related to timestamps. Could you run the following commands on both the XI machine, and the offloaded DB machine? Replace the SQL credentials as needed for the SQL machine. Some of these may fail, and that's fine. - grep "date....

Generally configuring NTP will keep a system's time accurate enough for most uses, but some edge cases c...

Lets check the time, according to various components, on your XI machine. Run this command and post the output: date; ntpdate; grep "date.timezone" /etc/php.ini; ls -l /etc/localtime; php -r 'echo date("D M j G:i:s T Y")."\n";'; mysql -uroot -pnagiosxi -e "SELECT ...

We've recently run into an issue where alerts show up several (sometimes as long as 45-60) minutes. When we restart Nagios (or do an apply) it appears to fix itself for a while; but it appears to happen approximately 24 hours. We're running Nagios XI 5.2.9 on a Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20G...

Sent you another PM with that info.

Just PM'd the logs to you.
