Usage Note 63168: A java.lang.StackOverflowError might occur when you run a project workflow that has many tasks in SAS® Risk and Finance Workbench
 |  |  |  |
In SAS® Risk and Finance Workbench, when you run a project workflow that has many tasks, a java.lang.StackOverflowError might occur. For example, a stack overflow occurs in the following scenario:
- The process definition for the workflow contains 10,000 tasks.
- The JVM_OPTS environment variable has a thread stack size setting (-Xss<value>) of 256k as shown in the following:
JVM_OPTS="-Xmx2048m -Xss256k -Xms1024m
When the stack overflow occurs, the log contains errors similar to the following:

To work around this issue, increase the thread stack size setting from 256k to 2m by updating the setenv.sh file in SASServer11, located here:
Linux and UNIX: SAS-configuration-directory/LevN/Web/WebAppServer/SASServer11_1/bin
Windows: SAS-configuration-directory\LevN\Web\WebAppServer\SASServer11_1\bin
In this file, update the JVM_OPTS as follows:
JVM_OPTS="-Xmx2048m -Xss2m -Xms1024m
After updating the thread stack size setting, restart SASServer11 to make the change take effect.
