Msg 845, Sev 17: Time-out occurred while waiting for buffer latch type 4 for page (1:27527325), database ID 10.
Msg 1823, Sev 17: A database snapshot cannot be created because it failed to start.
Msg 7928, Sev 17: The database snapshot for online checks could not be created.

Read on to learn more about Eitan’s troubleshooting process, what the cause of the issue was, and the fixes (both the immediate and complete ones) needed to resolve the issue.
