Are you able to get any resources from pool? Does it fail like this on the first attempt or on the 500th?

It looks like someone else has had this issue:

It says that ValidateObject failed. Validation in executing a PING command to redis. So if it fails, it means the PING command didn't get a PONG response, either because it got something else or the connection failed.

I would say that it seems like a connection issue. As Sam asked, does it happen on the first attempt or the 500th?
