StackOverflowError occurs on Web Server 7.0 running in 64–bit mode (6449977)

If Access Manager is configured on a Web Server 7.0 instance using a 64–bit JVM, the user encounters a Server Error message when accessing the console login page. The Web Server error log contains a StackOverflowError exception.

Workaround: Modify the Web Server configuration by following these steps:

1. Log in to the Web Server administration console as the Web Server administrator.

2. Click Edit Configuration.

   In the Platform field, select 64, then click Save.

3. Click the Java tab, and then click the JVM Settings tab.

   • Under Options, look for the minimum heap size entry (for example : -Xms). The minimum heap size value should be at least 512m. For example, if the heap size value is not -Xms512m or greater, then change the value to at least -Xms512m.

   • The maximum heap size value should be at least 768m. If the maximum heap size is not -Xmx768m or greater, then change the value to at least -Xmx768m.

   • Set the Java stack size to 512k or 768k by using -Xss512k or -Xss768k. You can leave it at the default size for 64-bit JVM on Solaris Sparc (1024k) by leaving it blank.

4. Click the Performance tab, then click the link "Thread Pool Settings.”

   Change the stack size value to at least 261144, and then click Save.

5. Click the "Deployment Pending" link in the upper right corner of the screen.

   In the Configuration Deployment page, click the Deploy button.

6. In the Results window, click OK to restart the Web Server instance.

   Click the Close in the Results window after the Web Server has been restarted.
