The HTTP 503 error may occur if there are too many requests being handled by the IIS server, causing the request limit to be exceeded.

To fix the issue:

Open the IIS Manager, then navigate to Application Pools > OfficeScan_iAC_AppPool and OfficeScan_iVP_AppPool > Advanced Settings.
1. Change [Queue Length] to 65535 (default: 1000).
2. Change [Maximum Worker Processes] to 2 or more (default: 1).
Change the IIS "appConcurrentRequestLimit" to 100000 (default: 5000).
1. You may run the following command via Command Prompt:
  c:\windows\system32\inetsrv\appcmd.exe set config /section:serverRuntime /appConcurrentRequestLimit:100000
2. Check if the setting below appears in the file. "%systemroot%\System32\inetsrv\config\applicationHost.config"
  <serverRuntime appConcurrentRequestLimit="100000" />
Restart the IIS Manager and the Apex One Master Service then redeploy the policy.
