Something like
vmstat 10 > vmstat.log

How many pgsql processes are there when this happens? Try something like
ps axu|grep postgres
to see. use
ps axu|grep postgres|wc -l
to get a rough count. I'm guessing that your web service layer is
keeping old connections open. could be something as ugly as php's
pg_pconnect or a buggy jdbc driver, etc...
