Every few minutes, one particular server will disappear for about a minute.
When I throw Domino Designer at it, it reports about 7 Database Server tasks' activity as "Buffer Manager I/O Thread".
Sometimes Domino Designer will even pop up a dialog that the server didn't respond in a reasonable amount of time.
Also, when trying to connect with this server the first time, often it takes 30-45 secs to get a connection to the server. "servername connected".
I'm not really sure where to look next.
I'd been researching that possibly the FT indexer was overused. I'd split out the indexer to its own thread, moved a bunch to hourly indexing. But the issue still occurs.
It seems everything's affected by the slowness: view refreshes are profoundly slower, and opening docs can get trapped by the 30-45 sec delay.
Any ideas or experiences like this welcome. It's become an ongoing frustration.
