I am running PostgreSQL 8.3.4 on Centos 5.2 with a single Xeon 5472, 1600 MHz, 12 MB cache, 3.0 GHz quad core, and 4 GB RAM.
My database is only about 50 MB and there are only about 20 users.
For some reason Postgres is pegging my CPU and I can barely log on to reboot the machine. After reboot all is well for another week or so, but this brings the system to a grinding halt.
What is the best way to debug this?
Can I limit Postgres to a certain number of cores or set the timeout on the queries to a lower value? I would greatly appreciate any advice on debugging this problem. While there are relatively live few users the data is extremely important and the users will not wait for me to see what is wrong. They demand immediate resolution and the best I can do is reboot.
