I have a process that updates ~ 1500 rows in a table once a second. Every 5 minutes (almost exactly) the update takes ~ 15 seconds (normally < 1). I have run htop/top on the machine during this time period and do not see anything unusual. I am running postgres 8.1.8 on a FC6 box. Any type of internal accounting/logging set to 5 minute intervals by default within postgres? Right now I am looking at pg_stats activity to see if there is anything there but so far have had no luck.
