Hi,
We've migrated one
of our servers from pg 7.4 to 8.1 and from times to times (4 hours) the server
start doing a lot of context switching and all transactions become very
slow.
The average context
switching for this server as vmstat shows is 1 but when the problem occurs it
goes to 250000.
CPU and memory
usage are ok.
What can produce
this context switching storms?
It is a box with
12GB RAM and 4 processors running RedHat Enterprise Linux
AS.
Thank you in
advance!
