We have a database running on a 4 processor machine. As time goes by the IO gets worse and worse peeking at about 200% as the machine loads up.
The weird thing is that if we restart postgres it’s fine for hours but over time it goes bad again.
(CPU usage graph here http://www.flickr.com/photos/8347741@N02/502596262/ ) You can clearly see where the restart happens in the IO area
This is Postgres 8.1.4 64bit.
Anyone have any ideas?
Thanks
Ralph
