Mass creation and deletes using powershell

I have a couple basic scripts that take arguments from a master workflow that executes them. Out of 20 requests one fails and that is not consistent. I have added logic if I see another delete action from my workflow running, I wait before executing the next one.

 

The script (delete only you get the idea): Add-PSSnapin iControlSnapIn

 

try {

 

$output = initialize-F5.iControl -HostName $F5device -Username $F5username -Password $F5password

 

$output = $(Get-F5.iControl).LocalLBVirtualServer.delete_virtual_server( (,$Name) ); return 1 } catch { return "ERROR:$_"

 

}

 

The script output...
