CNR and DNS resolving

Hi. We have two servers with CNR 5.5.7 these servers work in cluster, and sometimes one or both servers can’t resolve any external site. On each request displays message "request timeout". After hardware restart everything works perfect. Maybe somebody can give advice why these happen?

Re: CNR and DNS resolving

Hi zumbitribe.

The "request timeout" is pretty generic in nature, so I would need to see the dns log taken at the time of the problem to understand what is going on. If you upload it here, I'll take a look, otherwise if you're concerned that it contains sensitive information, you'll need to go ahead and open a TAC case on this.
