Issue/Introduction
This article describes a response to a stack overflow error.
Resolution
You can increase the stack size in CIS's JVM. Choose whatever number of MBs you need.
Use this JVM directive to increase as needed: -Xss4m
You will make the edits in this file: INSTALL_DIR/conf/script_env.sh
Complete instructions for modifying the jvm is documented in the Administration Guide, under the heading "Customizing the CIS Server Startup Scripts on <your os>"
This JVM topic is also discussed in the Studio online help.
