Possible Memory leak

Polaris Bug Report

Description of the bug

We have Polaris running in a windows container and over time it is consuming more memory.

A clear and concise description of what the bug is.

Steps to reproduce

Steps to reproduce the behavior:
Start Polaris as a windows container and monitor memory. At this point we aren't actively using the REST API.

Expected behavior

Start container and the amount of memory to start the process should be used and stay at a consistent amount.

Additional context

Dockerfile we are using
FROM mcr.microsoft.com/powershell:lts-nanoserver-1809

USER ContainerAdministrator

RUN setx /M PATH "%PATH%;C:\Program Files\PowerShell"

SHELL ["pwsh", "-Command"]

COPY artifacts C:

RUN ["pwsh.exe", "C:\bootstrap.ps1"]

Expose 8080

cmd C:\Invoke-Polaris.ps1

Entrypoint Script
Import-Module Polaris
New-PolarisGetRoute -Path "/test" -Scriptblock {
$Response.Send('DEVOPSAPI is running');
}

New-PolarisGetRoute -Path "/customers" -Scriptblock {
$getCust = "C:\scripts\get-customers.ps1" | Invoke-Expression
$Response.Json($getCust);
}

New-PolarisGetRoute -Path "/customers/:cid/workflows" -Scriptblock {
$cid = $Request.Parameters.cid
$getWFs = "C:\scripts\get-workflows.ps1 -CID $cid" | Invoke-Expression
$Response.Json($getWFs);
}

$wfkey = $Request.Parameters.wfkey
$getSteps = "C:\scripts\get-workflow-steps.ps1 -CID $cid -WFKEY $wfkey" | Invoke-Expression
$Response.Json($getSteps);
}
