Hello again, I tried to do some tests with YourKit. It seems that what increases the most is the amount of objects (and memory used by them) of java.util.HashMap$Entry class. Also java.util.HashMap$Entry[] is high in the list. Another thing I noticed: sometimes when the amount of free memory is really low, Tomcat somehow increases it (gets rid of old garbage?). You can see this effect on this new graph from Munin: http://logowanie.uw.edu.pl/tomcat_jvm-month.png The last increase of free memory (to almost 300MB) was not my restart, I wasn't doing anything on the server at that time. But after the increase the same things happen all over again.
