  • CPU Usage

    Since I moved to my VSP I hit a few times issues on CPU going bezerk and hitting the roof. Yesterday I had those issues in the same day.
    The 1st one is plenty of logonui.exe and winlogon.exe processes making the CPU growing. I fixed it by tracking down the IP addresses (2 yesterday) causing the issue and blocked them thru my firewall.
    The 2nd one ocurred at 3AM this morning and my monitoring system woke me up. This time PHP.exe was using all the CPU available and stalled the website. I connected to the server killed the service and everything went back to normal.

    I managed to handle those 2 situations myself but I would like to prevent them from ocurring. Any experience around ? I don't know why php.exe is behaving like that, my server is a Windows 2008 R2 and I am not using php as I am a .NET guy. But perhaps any service does (Plesk ?), I don't know.

    Any idea around ?

    Hi Corobori,

    The first issues with the logon attempts from remote IPs, the best solution there is to change your default RDP port. We have a KB article here on the subject:

    Only change i would make is to be sure the port you would like to use is open on the firewall before making the change rather than after

    On the php process, it is definitely possible to disable for use outside of Plesk related functions. If you log into Plesk and take a look at the components page you can remove php components entirely. This will at least confirm that it's not some random test script being hit or anything outside of Plesk itself.

    If you determine it to be Plesk after that, i would take a look at any Scheduled Tasks configured in Plesk that are queued for around the time of your spike or anything that runs a php script for that matter.

      Disabling php doesn't seem doable. See the message I got:
