Thanks, will try.
For the peanut gallery and google, since the portal's search function did
not help me at first (seems to be case sensitive search, or a broken full
text index? In any case, I *did* search for OutOfMemory and this article
didn't come up :-(
in /usr/share/tomcat/bin/catalina.sh
-> JAVA_OPTS=" -server -ms20M -mx512M "
(important is the -mx value. We used 1024M since the machine is big enough)
And in /etc/tomcat/base/jk2.properties
-> request.registerRequests=false
which is said to avoid triggering a memory leak.
cheers

This is what open source software is all about: creating knockoffs and
giving them away, destroying the value of whatever the other guy is
selling.
