The server is running Postgres 8.2.4
When the server is doing too much operations like I, U or D the postgres stop a while each 5 min...!
I mean "stopping" that I don't receive any response from postgres, and the process the all people are running stay there, waiting for something.
I read a several names to it like: gap, stall, slowdown... I don't know the write _expression_ for this situation.
I hope you can help me.

Hello there,I'm having some slowndowns in my postgresql server, and I had been reading something about checkpoints, that could resolve my problem.Now, I have:checkpoint_segments = 30 # in logfile segments, min 1, 16MB each#checkpoint_timeout = 5minAnd I percebed that this slowndown is occuring for 5 min...! So I'm suposing that the problem is in the checkpoint_timeout.What's the impact to chang it to:checkpoint_timeout = 2min orcheckpoint_timeout = 5minTnhks,Rafael Domiciano
