On a virtual server we have a bunch of projects saved. These project each relate to a published portal map image layer that we consume as a map service in our applications.
Recently (as in the last month) one of these projects started to only open in read only mode which is mildly inconvenient if you want to make changes to the published service. Originally I assumed someone was accessing it. However, because its a locked down VM it was pretty easy to ask the people who have access to the VM if they have it open. They didn't have it open. I also tried turning off the service that accesses it assuming that may be causing it for some off reason, it wasn't. Its only one project on a drive with a whole bunch of them, but I'm just worried it will start happening to more of them.
I've also tried just opening the project and saving it as a different name (creating a new project). This brand new one now only opens in read only mode as well.
After reading through some articles about similar instances I've done about everything I can do.So I'm at a loss for trouble shooting, hopefully someone else has seen this behavior.
Service was published out of pro 2.5.1 which is still the current version of pro used on that VM.
