In /etc/tomcat5/tomcat5.conf, there are some settings related to heap. They are in the JAVA_OPTS setting (see -Xms and -Xmx).
It is suggested to customize such settings taking into account how much physical memory is available, as indicated in the following table (which refers to 64bit architectures):
| Memory | < 2 GB | 2 - 4 GB | > 4 GB |
|---|---|---|---|
| JAVA_OPTS setting | -Xms128m -Xmx512m | -Xms512m -Xmx1024m | -Xms512m -Xmx2048m |
After having done the changes, it is necessary to restart tomcat
