Hi!Robert,We at MusicBrainz have been having trouble with our Postgres install for the past few days. I’ve collected all the relevant information here:If anyone could provide tips, suggestions or other relevant advice for what to poke at next, we would love it.
Wow - You've engaged the wizards indeed.
I haven't heard or seen anything that would answer my *second* question if faced with this (my first would have been "what changed")....
What is the database actually trying to do when it spikes? e.g. what queries are running ?
Is there any pattern in the specific activity (exactly the same query, or same query different data, or even just same tables, and/or same users, same apps) when it spikes?
I know from experience that well behaved queries can stop being well behaved if underlying data changes
and for the experts... what would a corrupt index do to memory usage?
