title: Cannot allocate a new connection: 16 connections already opened RMySQL
body: <p>I am very new to shiny and R but using shiny I am trying to connect to a database fetch the data from there. When I try to access my RShiny work on browser continuously I got an error like <code>Cannot allocate a new connection: 16 connections already opened</code>. How can I overcome this error or RShiny only expecting 16 users at a time? I have got another stack post here <a href="https://stackoverflow.com/questions/24649673/rstudio-shiny-error-mysqlnewconnection-maxinum-of-16-connections">RStudio Shiny Error mysqlNewConnection maximum of 16 connections</a> but the explanation was not clear on the above URL. </p>
