(WinXP, PG8b5, 1GB, 3,2GHz)
Hi,
I regulary get the above error message when I run my applications in
parallel. There are minimum of 5 applications which have to access the
server in parallel, but in the production environment this number will about
30-50 (with the additional clients). Each of them connects to the server
(here comes the error message), runs a query and disconnects.
If one of them is stopped, then everything works well, but 5 applications
seem to be too large.
I monitor the PGAdmin Server Status window. It shows that maximum 2
connections are concurrent in the same time, not more.
My postgresql.conf file:
max_connections = 100
shared_buffers = 20000 # min 16, at least max_connections*2, 8KB
each
work_mem = 16384 # min 64, size in KB
maintenance_work_mem = 16384 # min 1024, size in KB
max_stack_depth = 2048 # min 100, size in KB
(The NT Task Manager reports a 769MB memory usage.)
What should I increase/decrease to acheave the required performance? Or what
do I do wrong?
Many thanks,
