Hey Steven
Thanks for your help.
So far. after looking at the error messages, we did not see any helpful message. I will be on the lookout.
I noticed in the logs some messages such as the message below.
The machine is a Windows machine, with an SSD hard drive. It has 8 Gigs of memory, Event Store occupies 1.8G.
I have a hunch that it is a timeout setting (for the projection computation) but don’t know how to change it, nor why it is happening.
