Sounds more like a bug in the application rather than an OS thing. Have you tried checking with the application support team? Does the application log any error about shutting down ports?
I have seen Java applications delay in opening ports. But, shutting down a listening port is different, may be due to some restriction in the application's config, etc. In your situation, I would seek help from the apps team.
