I run various queries against a SQL Server 2012 instance, and occasionally, the following error message will pop up:
The connection must be in an opened state.
Parameter name: connection (SQLEditors)
Although it usually happens while I've left that particular tab idle in SSMS for a while (~10-45 minutes), it also sometimes happen in between running queries nearly back-to-back. The connection state at the bottom will always say "Connected" before I run the query (and obviously immediately change to "Disconnected" when that error shows up).
The database's AutoClose option is disabled, and I also have the "Disconnect after the query executes" option disabled locally. There aren't any scheduled jobs I can find that might be routinely disconnecting queries. Help? Ideas?
