event viewer errors

[jjroman]

I have many times this error in the Event Viewer:

Unexpected parameter *******(client)(pool). Possible parameters is:
--pool-name
at (Params::check line 118)
at execute console command --get-app-pool(vconsoleapp::start line 129)
at execute "C:\Program Files\Parallels\Plesk\admin\bin\websrvmng" --get-app-pool "--pool-name=******" ********(client)(pool)(vconsoleapp::run line 140)
Execute file name: C:\Program Files\Parallels\Plesk\admin\bin\websrvmng.exe

What Can I Do?
