Hello, 

we have CAS 3.0.7 running on Tomcat 5.5 + Apache2. CAS is the only thing 
running there on Tomcat. 

Everything is fine except for the amount of memory used by Tomcat. It seems 
that as time goes by, Tomcat uses more and more memory. Here is a picture 
generated by Munin: http://logowanie.uw.edu.pl/tomcat_jvm-month.png 

After restart suddenly everything seems to be fine again, there is a lot of 
free memory, but as time goes by, the situation is getting worse. You can 
see exactly on the picture when I was restarting Tomcat. 

What could be the cause? Is it a memory leak in CAS? It seems that we have 
to restart Tomcat once a week or so, but I would rather fix the cause 
itself. 

Regards,
Dominika
