This is a strange one. I am typing a query in SQL Server Management Studio. Nothing is executing on the server. I actually get an hourglass as I type the query at which point I am forced to wait up to 10 seconds before I can type again. I may get one word typed before I get another hourglass.
I tried to RDP to the server directly (thinking it may be something on my computer) and the problem happened there as well. I did a task manager and all the processors were maxed out and the memory usage was maxed as well. SSMS was using 100% of the server.
Again, nothing was executing.
