if you already have enough ram, you still have to tell the jvm
that it's allowed to use it. Therefore use the environment
variable JAVA_OPTS. On Linux in my catalina.sh script i added
a line like this:
JAVA_OPTS="${JAVA_OPTS} -Dsun.net.client.defaultConnectTimeout=200 -Xmx512m"
That gives the jvm a maximum of 512 MB RAM.
BTW: in development i experience, that after i compiled and deployed my portal
several times on tomcat 4.1.x, which works fine without any restarts, i evetually
get Out of memory errors anyway, which i can solve by restarting tomcat.
