Hello Vladimir, I run a busy website with debian tomcat 4.1.31 and I suffer the same memory problems you pointed at.
Unfortunately tomcat 5.5.x is not packaged for debian (nor I heard of any plans for it), but I'm using with success tomcat 5.0.28 that you can find at: http://apt.leapster.org/tomcat/ add the following line to sources.list if you want to use it: deb http://apt.leapster.org/tomcat/ ./ I hope that debian tomcat mantainers could start from that source to prepare an official debian package, it would be *very* appreciated since tomcat 4.x is almost left unmantained from upstream.
