Due to a memory leak in MMON, we kill it nightly and the database automatically restarts it.

Ah, that actually makes sense. It does seem an odd state to be in.

Honestly, if it was me, I'd take my lumps, get approved to do a 'startup force' (likely the quickest way to complete bounce) and be comfortable that there are no lurking surprises....:-)

I inferred from Charles' original message that they the shutdown of the database was inadvertent, and that they had managed to cancel it before the shutdown had actually completed. The database was still "up" (at least from the user's perspective) and he was now looking for a way that he might salvage it without any downtime to the end users.
