Hi, I've take a memory dump of one of our production instances and I'm seeing about 500MB of memory consumed just by the DiskDataStore which doesn't seem correct to me. Here is a screen shot: https://customerservices.glasscubes.com/share/s/qmvnvrdtm36amme6sdrqg4dp2g
I've highlighted the item - 524,288 items doesn't seem correct for ~500 http sessions?. It seems to me that removeData(*final* String sessionId) is probably not being called and clearing up the sessionEntryMap. Looking at the call hierarchy I can see how Jetty calls it but I cannot see how tomcat is calling it. Any ideas whats happening? Wicket 7.8.0, Tomcat 8.0.32 Thanks
