Cause

The new features introduced in DPA 2025.4.0.511 increase the startup workload, requiring a larger Java stack size than the default 300k. The default stack size is insufficient, preventing necessary startup tasks from completing and causing the application to fail with a 404 error.

Resolution

To resolve this issue, increase the Java stack size by modifying the server.properties file:
  1. After installing or upgrading to DPA 2025.4.0.511, locate the file:
    dpa_2025_4_0_511/iwc/tomcat/ignite_config/idc/server.properties
  2. Open server.properties in a text editor.
  3. Find the line starting with:
    java.stack.size=
  4. Change this line to:
    java.stack.size=600k 
  5. Save the file.
  6. Restart DPA using the startup script:
    ./startup.sh
After these changes, DPA should start successfully, and the web interface will be accessible.
