Add this line to your catalina.sh file under environment variables: export JAVA_OPTS=-Xmx512m

If you don't have a GB of memory, modify the "512" to an appropriate level relative to your memory size. -----Original Message----- From: Burak "Yýlmaz [mailto:[EMAIL PROTECTED] Sent: Friday, February 10, 2006 9:45 AM To: users@tomcat.apache.org Subject: Tomcat out of memory Hi all; I have a web site where 200 users online at average...These user overload started in these days...
