Hi Sridhar,

What HostSupplier are you using in Dyno? https://github.com/Netflix/dyno/wiki/Configuration#hostsupplier

Hi Sailesh, Thanks for your reply. Issue resolved after increasing the MaxConnsPerHost . Earlier default MaxConnsPerHost value 3 is used.

Below host supplier is used

`public HostSupplier getHostSupplier() {

             hostSupplier = new HostSupplier() {

                @Override
                public List<Host> getHosts() {

                    return Collections.singletonList( new Host('localhost', 8102, 'rack', Host.Status.Up));
                }
            };

    return hostSupplier;
}`
