Problem Note 55904: You cannot access any SAS® 9.4 web applications when the secondary middle-tier node is in a clustered environment
When you start the SAS 9.4 secondary node for the middle-tier node in a clustered environment, you cannot load any SAS 9.4 web applications after you enter your user ID and password. When this problem occurs, the Microsoft Internet Explorer browser runs in a continuous loop, and the following errors appear in the SAS Web Server log file:

However, you can access the SAS 9.4 web applications when only the primary node in the middle tier runs in a clustered environment.
To solve this problem, follow these steps:
- Add the following Java virtual machine (JVM) argument to the JAVA_ARGS option on your middle-tier machine:
-Dgemfire.conserve-sockets=false
- For UNIX operating environments, add the argument to the section that is labeled # Java Additional Parameter in the gemfire-start-locator-sas.sh script file, which resides in the SAS-configuration-directory/Lev1/Web/gemfire/instances/ins_41415/ directory.
- For Microsoft Windows environments, add the argument to the section that is labeled # Java Additional Parameter in the wrapper.conf file, which resides in the SAS-configuration-directory/Lev1/Web/gemfire/instances/ins_41415/ directory.
- Add the same argument (-Dgemfire.conserve-sockets=false) JVM_OPTS arguments for all instances of the SAS 9.4 Web Application Server (for example, SASServer1_x, SASServer2_x, and so on).
- Under UNIX, add the argument to the section that is labeled # Java Additional Parameter in the setenv.sh script file, which resides in the SAS-configuration-directory/Lev1/Web/WebAppServer/SASServer1_x/bin/ directory.
- Under Windows, add the argument the section that is labeled # Java Additional Parameter in the wrapper.conf file, which resides in the SAS-configuration-directory/Lev1/Web/WebAppServer/SASServer1_x/conf/ directory.
- Restart the SAS 9.4 middle-tier services in the clustered environment.
