i have an environment here (DSM 2016.2) were i see some patches going red after 3 retries. When i analyse the logfile, i can see the LPRInstallPatch command returns a return code "144". It also tells me, this is not a windows error code. So obviously PatchLink is working with some kind of internal return codes. Which is OK though, but i'd like to have a list of those codes for me to do better troubleshooting.
Does anyone know if such a list exist and were to get it? Or do i have to contact support and ask for it there?
