Error description
In DB2 environments where a per user license policy is enabled, an application calling a DB2 API can trigger the license daemon to be started. On Unix systems, the license daemon will inherit all of the parent process' file handles. The license daemon is a long-running process, and so any inherited file handles (which include sockets) will be held open indefinitely.
Local fix
Modify the application so that it does not open files or sockets in a mode which allows them to be inherited by any child processes. In environments where this is not possible (such as a 3rd party application), the license daemon can be started on the command line by typing 'db2licd'. This ensures it will not be spawned from an application process.
