Event store projections failing on a regular basis

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.
