debain keeps going down

debain keeps going down

I am not sure what is happening and I cant get a hold on the situation due to I can access the server from my Ubuntu.
3 out of 10 times I am getting this error
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
    Someone could be eavesdropping on you right now (man-in-the-middle attack)!
    It is also possible that a host key has just been changed.
    The fingerprint for the RSA key sent by the remote host is
    54:57:1a:13:7c:d5:07:c8:40:76:2d:ac:56:03:31:3a.
    Please contact your system administrator.
    Add correct host key in /home/pckhanh/.ssh/known_hosts to get rid of this message.
    Offending RSA key in /home/pckhanh/.ssh/known_hosts:6
      remove with: ssh-keygen -f "/home/pckhanh/.ssh/known_hosts" -R 192.168.1.150
    RSA host key for 192.168.1.150 has changed and you have requested strict checking.
    Host key verification failed.
I am wanting to know why something like this would happen
Nagios is showing the following

and the history report show this
