Error: HTTP Status 404 - Not found after upgrading DPA to 2025.4.0.511 (Linux environment)

After upgrading DPA Linux environment to 2025.4.0.511, the DPA web interface returns "HTTP Status 404 - Not found" error. 

The Java stack size configured in the DPA server.properties file was insufficient for the environment.

1. On the DPA server, locate the server.properties file. For DPA 2025.4.0.511, the path is:

   dpa_2025_4_0_511/iwc/tomcat/ignite_config/idc/server.properties
   

   (adjust the base folder name if your installed DPA version differs).

2. Open server.properties in a text editor with appropriate permissions.

3. Find the line that starts with:

   java.stack.size=
   

4. Set the Java stack size to 500k by updating the line to:

   java.stack.size=500k
   

5. Save the server.properties file.

6. Restart DPA using the startup script, for example:

   ./startup.sh
   

After performing the steps above, DPA should start successfully.
