Hi I'm running a continuous loop, and running into a memory issue

$date=(get-date).day
while($date -eq ((get-date).day))
{
   
    Start-Sleep -Seconds 10
   

}

memory consumption of powershell.exe increases over time is there a way to keep it in check for this simple loop?

You can try adding in garbage collection to your loop and see if it will free up the memory.  It's a .NET class you could call every 100 iterations (or so).

$i = 0
$date=(get-date).day
while($date -eq ((get-date).day))
{
    Start-Sleep -Seconds 10
    
    Write-Host OK...
    if ($i -eq 100)
    {
        [System.GC]::Collect()
        $i = 0
    }
    $i++
}

Do you really run only this simple loop? Certainly not - and then the other stuff might be the culprit.
If all you do the loop for is to wait, then you should just run a single sleep with the correct number of seconds.

i ran this simple loop and the [GC.System]::Collect does prevent the powershell.exe thread from increasing in memory. (You can test yourself)
I have it running every 15 minutes on my current service
I do have a complex process running based on user demand, and the working memory on the iis server is not increasing in size
