Hi!
Yes, that is indeed the problem.
I tried the recommended settings for sysctl.conf. Now ard and
postgresql are working well together.
Now i am ongoing to optimize the settings. Without changing the
sysctl.conf or rc, i am able to get postgres running with the
following settings:
max_connections = 40
shared_buffers=640kB
Does anybody see any problems with theese settings? The amount of
parallel connections should not be a big problem, because it is a
dedicated database.
Thanks Tom and best Regards,
Peter
