Hi Naresh, One thing that may be worth doing is to run a local caching DNS server. This can help prevent transient DNS problems with your ISP from tanking your RT performance. The best one that I know of and that we use on our RT system is called pdns-recursor-3.3. You can get it from www.powerdns.com as a free download. I am glad that you got it all working again.
