title: Big number of http sessions in grails
body: <p>I'm running grails 2.2.4 app on tomcat7 and Linux server. I see in JavaMelody monitoring (plugin) that there are over 1000 http sessions opened while only about 10 users are logged in. What's more, all those sessions not connected to users (I can see username if it is) have serializable size of 1.607b (users sessions have -1b).</p>
  
  <p>I'm curious if there's something wrong with that - I have other app, very similar in size, running on the same server with over 200 users and also about 200 sessions - and, if there is, what can I do to fix that or find the cause.</p>
  
  <p>Any help would be appreciated.</p>
