The profile shows the xagt command is using the most CPU. It may be worth testing having this disabled.

Also, how are you testing to confirm they are false alerts? The logs I see how ping responses taking 3+ seconds. The plugin XI uses will rely on the ping binary of the system. When you get an alert about a host being down, try pinging the 'down' host from the command line. For example:

Code: Select all

ping LXACPSEA

A ping could fail for number of reasons and not just if the server is down. Routing, network issues, or a firewall blocking icmp traffic for example. As seen in the profile, some of these are not completely failing - some are getting an 80% return which could mean packets are getting dropped somewhere.
