Keep an eye on free memory -- one of our similar systems has to be restarted every 60 days to prevent the behaviour you're encountering. We haven't determined the source of the memory leak, but if we permit it to continue eventually the DB stops responding and cannot be shut down. This system does some analytical work for us so it has different connection and activity profiles than the others, so I've a limited basis for comparison, but the other 8.1.5 databse (this one's data source) shows similar problems over a longer period. My plan is to take it up to 8.1.7 as those systems are not showing that sort of problem.
