Move to the latest 1.1.x JDK. 1.1.6 has some known issuesw with threading
and memory leaks I believe. Also, make sure that you are giving the JDK heap
enough memory.

Wow, that is a lot. ;-( With 1.0.1, we will hopefully have a patch that
decreases the number of env variables that are passed around and thus the
number of string objects that are created.

How about using these configuration values in jserv.properties to only pass
the env variables that you need?
# An environment name with value passed to the JVM
# Syntax: wrapper.env=[name]=[value]
# Default: NONE on Unix Systems
# SystemDrive and SystemRoot with appropriate values on Win32 systems
# An environment name with value copied from caller to Java Virtual Machine
# Syntax: wrapper.env.copy=[name]
# Default: NONE
# Copies all environment from caller to Java Virtual Machine
# Syntax: wrapper.env.copyall=[true,false]
# Default: false
