UIOP uses filesystem tokens to identify endpoints. By default these are named /tmp/TAOsomething, but they can also be whatever you specify. When your server ORB is shut down, it will clean up the token associated with any UIOP or SHMIOP transport. However on a crash, the endpoint token remains in the filesystem, and will cause a re-run of the server to fail. SHMIOP uses a filesystem entry per connection which serves as the shared memory identifier.
