Database won't shutdown immediate

Hey there,
Our system is set up to kick off a script at night to shutdown the database (Oracle 7.1.3 on Digital Unix 3.2(D I believe?)). For the past few weeks, the shutdown has hung. The are no ORA errors listed in the alert log at this time...the log simply states that oracle is attempting to shutdown immediate and nothing is printed after that. We have been having to log in, do a shutdown abort, startup and shutdown normal. This has worked every time. This problem has only surfaced within the last couple of weeks and the only thing that I am aware of changing since then is a CPU upgrade to the server. There are occassional days when it does completely shutdown on it's own, but more and more frequently it is hanging. A database link does exist between this oracle instance and another on the box, however that has alwasy existed, and has never caused a problem such as this before. Still, could there be something up with this link to keep the one instance from fully shutting down most of the time (but not all)? We have attempted to shut down the other instance first, then the troublesome one, however in this situation the shutdown also hun, this time giving us an error message saying that it was waiting for logins to complete. Once we started up the other database, the shutdown completed. If anyone has seen anything like this, or has any advice, suggestions, etc...it would be greatly appreciated.

Thanks!
