AD Connect hangs synchronizing local AD to Azure AD
We are using latest Azure AD Connect tool (1.1.371.0) on WS2012R2 server (2CPU, 2GB RAM, Hyper-V virtual machine). In a few months synchronization has hanged 3-4 times. I usually reboot whole server ...
We had some cases where our Sync process hung and a server reboot was required.
We finally traced it back to a SQL maintenance job that we had running on the SQL database - you may want to check that if you are using a full SQL implementation.
We are using the built-in (Express?) database provided by AD Connect itself. We probably can't tune that (or shouldn't even). On another thread it was suggested to give it more RAM. It was 2 GB originally. I have increased it to 4 GB and it is running fine for 1-2 weeks so far. But i'm still hesitant to call it 'solved'. Need to monitor longer.
- Yah - I would not make any changes to the Express DB.
Hope the RAM is the solution.
