title: "Too many open files" on Tomcat Keystore
body: <p>I've recently started getting an error on our Tomcat servers : "Too Many Open Files" and the error goes on to reference the keystore file used for the server's SSL connector.  Does anybody have any idea where this could be coming from ? Our server receives a considerable number of connections, but if I push the maximum acceptable connections past 150, the server won't even start (for whatever reason).  Is there any way to get Tomcat to cache the keystore in memory so that connections don't have to read from the file repeatedly ?  </p>
