System.Net.WebException: The operation has timed out on EC2

[lunarjetset]

Hi,

I wrote a question on stackoverflow last night which Oren answered regarding timeout and he asked - are you running on this on EC2.  Yes is the answer and we are getting these issues again under load.  Why did you ask about EC2 Oren - are there potential issues there?

[Oren Eini (Ayende Rahien)]

If you are using on EC2, what instance type do you use? How do you run RavenDB there?

EC2 IO can be slow, so that might be an issue.

Hi Oren,
We are using a hi cpu instance with data and raven on one attached
drive and indexes on another. it's running as a service.
We are connecting from the same zone from appharbor instance.

thanks
Pete

Can you check the event log? We will give you warning there for slow IO.

Assuming that you are running on a medium instance, the IO speed you are getting from EC2 is probably poor.

Nothing in the Application Event Log so maybe not down to slow io.

The instance size is pretty big - hi cpu and mem.

Is it ok having raven and data on one attached drive and index on
another?

that instance size has only medium io. The instance is also running
an sql server database
