Hi,

=20

We're running postgres7.3 on RedHat7.3. The Postgres at boot time is
started up from a java (1.2) class that runs the following commands in
order:

=20

/usr/local/pgsql/bin/pg_ctl -w start -D /var/lib/pgsql -l
/var/log/pgsqld.log -o -i

/usr/local/pgsql/bin/createdb management

=2E

=2E

=2E

=20

As you can tell the postmaster starts up with "-i" option here.=20

=20

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

In pg_hba.conf we have:

local   all         all
trust

host    all         all         127.0.0.1         255.255.255.255
trust

host    all         all         192.168.0.0     255.255.0.0
trust

=20

The host IP address is 192.168.55.5 which is in the right subnet.

In postgresql.conf:=20

#

#       Connection Parameters

#

tcpip_socket =3D true

#ssl =3D false

=20

max_connections =3D 64

#superuser_reserved_connections =3D 2

=20

#port =3D 5432=20

#hostname_lookup =3D false

#show_source_port =3D false

=20

#unix_socket_directory =3D ''

#unix_socket_group =3D ''

#unix_socket_permissions =3D 0777 # octal

=20

As you can see tcpip_socket =3D true

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Sometimes, after Postgres starts up, when the database clients try to
access the db from the localhost, we get the following error:

=20

com.solarmetric.kodo.Runtime -
com.solarmetric.kodo.runtime.FatalDataStoreException: Connection
refused. Check that the hostname and port are correct and that the
postmaster is accepting TCP/IP connections.=20

=20

Any ideas what's causing postmaster NOT to accept connections some of
the time?

=20

This problem almost always goes away upon rebooting the machine.

=20

Any help is much appreciated.

=20

Thanks,

-Allen
