Hi
You might want to verify couple of things to ensure that the server is starting with the right permission
- permission of the logs directory (ls -la <install-root>/logs
- which server user is configured within web server's config/magnus.conf (the user mentioned here should have permission to write to the logs directory)
- which server user is actually starting the server. (the user here should have permission to write to logs directory)
besides, sun web server related questions are discussed in length here
